Find the principal which yields a simple interest of Rs. 20 and compound interest of Rs. 30 in two years, at the same percent rate per annum?  Choose the correct choice from the following choices
A) s. 20  B) s. 48  C) s. 42  D) s. 20  E) s. 60

Solution: Explanation:   SI in 2 years = Rs. 20, SI in 1 year = Rs. 10   CI in 2 years = Rs. 30   % rate per annum = [(CI – SI) / (SI in 1 year)] *100   = [(30 – 20) / 20] * 100   = 50 % p.a.   Let the principal be Rs. X   Time = T = 2 years   % rate = 50% p.a.   SI = (PRT/100)   20 = (X*50*2) / 100   X = Rs. 20   s. 20NSWER: s. 20

If the function Q is defined by the formula Q = 5w/(4m(z^2)), by what factor will Q be multiplied if w is quadrupled, m is doubled, and z is tripled?	Select:
A) 1/9 B) 2/9 C) 4/9 D) 3/9 E) 2/27

Solution: We just need to find the factor thats all,   w -> quadrupled -> 4w   m-> doubled -> 2m   z-> tripled -> 3Z   Hence, Z^2 = 9Z^2   W is in numerator, and m*z in denominator.   Hence,   Additional factor being introduced = 4/2*9   =4/18 = 2/9 = 2/9

Rectangular tile each of size 45cm by 50cm must be laid horizontally on a rectangular floor of size 250cm by 180cm,such that the tiles do not overlap and they are placed with edges jutting against each other on all edges. A tile can be placed in any orientation so long as its edges are parallel to the edges of floor. No tile should overshoot any edge of the floor. The maximum number of tiles that can be accommodated on the floor is:  Select
A) 35	B) 40	C) 25	D) 18	E) 20

Solution: Area of tile = 45*50=

Vijay bought 160 shirts at the rate of Rs. 245 per shirt. The transport expenditure was Rs. 1400. He paid an octroi at the rate of Rs. 1.75 per shirt and labour charges were Rs. 320. What should be the selling price of one shirt, if he wants a profit of 20%?	Choose the correct choice from the following answers:
A) Rs. 258
B) Rs. 270
C) Rs. 277.5
D) Rs. 309
E) None of these

Solution: Total CP per shirt = 245 + 1400/160 + 1.75 + 320/160 = Rs. 257.5   SP = CP[(100 + profit%)/100]   = 257.5 * [(100 + 20)/100] = Rs. 309.   ANSWER:Rs. 309

A man cheats while buying as well as while selling. While buying he takes 11% more than what he pays for and while selling he gives 20% less than what he claims to. Find the profit percent, if he sells at 9.09% below the cost price of the claimed weight.	Choose the correct choice.
A) 19.81%  B) 20%  C) 37.5%  D) 25%  E) 42.86%

Solution: There is a one step calculation method too. It requires more thought but is faster.   The man takes 11% more than what he pays for. So if he claims to take 100 pounds, he pays $100 but he actually takes 111 pounds for which he will take from the customer $111. Hence, in effect, there is a 11% mark up.   While selling, he sells 30% less. This means, he claims to sell 100 pounds and gets $100 but actually sells only 70 pounds and should have got only $70 for it. So this is again a mark up of $30 on $70.   But he also sells at 9.09% less i.e. gives a discount of 1/11.   (1 + m1%)(1 + m2%)(1 - d%) = (1 + p%)   11/10 * 10/7 * 10/11 = (1 + p%)   profit % = 42.86%42.86%

Fresh grapes contain 80% by weight while dried grapes contain 20% water by weight. What is the weight of dry grapes available from 40 kg of fresh grapes? Choose the most appropriate option:
A) 10 kg  B) 12 kg  C) 15 kg  D) 16 kg  E) 20 kg

Solution: From the question we know: 40kg * 80% = 32kg of water in the fresh grapes   40kg - 32kg of water = 8kg of non-water mass   We are looking for the weight of the dry grapes (X).   Since the question tells us that 20% of the weight of the dry graps is water and we know that 8kg is non-water mass we can set up the following equation:   X = 1/5(X) + 8kg   4/5(X) = 8kg   X = 10 kg   10 kgnswer- 10 kg

The water from one outlet, flowing at a constant rate, can fill a swimming pool in 16 hours. The water from a second outlet, flowing at a constant rate, can fill the same pool in 12 hours. If both outlets are used at the same time, approximately what is the number of hours required to fill the pool?  Choose the correct choice:
A) 0.22  B) 0.31  C) 2.50  D) 3.21  E) 6.85

Solution: Always remember RT=W i.e Rate*Time = Work   Also remember that rate can be added or subtracted. For e.g if A do a work in 2 day and B do a work in 2 day.   They both of them together will do a work in 1 day.   So now your question first determine both outlets rate.   1st outlet rate = 1/16 (R=W/T here W=1 work, T = 16hrs)   2nd outlet rate = 1/12 (R=W/T here W=1 work, T = 12hrs)   Both of them working together rate = 1st outlet rate + 2nd outlet rate = 1/16+1/12 = 7/48   again apply the formula RT=W   T = W/R = 1/7/48 = 48/7 =6.85   Answer is 6.85.

It has later found that the height of one of the boys in the class was wrongly written as 166 cm whereas his actual height was 106 cm. Find the actual average height of the boys in the class (Round off your answer to two decimal places?  Select.
A) 187.89 cm  B) 181.29 cm  C) 123.98 cm  D) 149.98 cm  E) 146.89 cm

Solution: Calculated average height of 35 boys = 183 cm.   Wrong total height of 35 boys = 183 * 35 cm. This was as a result of an actual height of 106 cm being wrongly written as 166 cm. Correct total height of 35 boys = 183 cm - (166 cm - 106 cm)/35   = 183 cm - 60 /35 cm   = 183 cm - 1.71 cm = 181.29 cm.   Answer: 181.29 cm

A sum of Rs. 2743 is lent into two parts so that the interest on the first part for 8 years at 3% per annum may be equal to the interest on the second part for 3 years at 5% per annum. Find the second sum? Select the correct option.
A) 1642  B) 1640  C) 1632  D) 1688  E) 6386

Solution: (x*8*3)/100 = ((2743 - x)*3*5)/100   24x/100 = 41145/100 - 15x/100   39x = 41145 => x = 1055   Second sum = 2743 – 1055   =1688   Answer:1688

India has a run rate of 3.2 in the first 10 overs. What should be the run rate in remaining 40 overs to win a game of 282 runs?	Choose the correct answer
A) 6.25  B) 6.27  C) 6.22  D) 6.21  E) 6.20

Solution: Explanation:   Runs scored in first 10 overs:   => Rate*Overs= 3.2*10= 
3.2*10 = 32
32 runs=> Required runs = 282-32= 
282-32 = 250
250=> Left overs= 40   Required rate = runs/overs   = 250/40= 
250/40 = 25/4 = around 6.25
6.25=> 6.25 runs per over is needed to win the game.   6.25NSWER: 6.25

Answer: A
Two trains A and B starting from two points and travelling in opposite directions, reach their destinations 9 hours and 4 hours respectively after meeting each other. If the train A travels at 110kmph, find the rate at which the train B runs.  Answers:
A) 40	B) 165	C) 120	D) 80	E) 100

Solution: If two objects A and B start simultaneously from opposite points and, after meeting, reach their destinations in ‘a’ and ‘b’ hours respectively (i.e. A takes ‘a hrs’ to travel from the meeting point to his destination and B takes ‘b hrs’ to travel from the meeting point to his destination), then the ratio of their speeds is given by:   Sa/Sb = √(b/a)   i.e. Ratio of speeds is given by the square root of the inverse ratio of time taken.   Sa/Sb = √(4/9) = 2/3   This gives us that the ratio of the speed of A : speed of B as 2:3.   Since speed of A is 110 kmph, speed of 165 must be 110*(3/2)= 
110*(3/2) = 165
165 kmph   Answer 165
Answer: B
Rs. 800 becomes Rs. 956 in 3 years at a certain rate of simple interest.If the rate of interest is increased by 4% ,What amount will Rs. 800 become in 3 years ?
Select the correct option:
A) Rs. 1020.80	B) Rs. 1025	C) Rs. 1052	D) Data inadequate	E) None of these

Solution: Solution   S.I. = Rs.(956-800 )=Rs.156   Rate = (100x156/800x3) = 6 1/2%   New rate = (6 1/2 +4)% = 10 1/2%   New S.I. = Rs.(800 x21/2x3/100) Rs. 252.   ∴ New amount = Rs.(800+252)= Rs. 1052.   Answer Rs. 1052
