A and B can do a piece of work in 18 days; Band C can do it in 24 days A and C can do it in 36 days. In how many days will A, Band C finish it together?  Select.
A) 15 days B) 12 days C) 8 days D) 16 days E) 9 days

Solution: Sol. (A + B)'s 1 day's work = (1/18) (B + C)'s 1 day's work = (1/24)   and (A + C)'s 1 day's work = (1/36)   Adding, we get: 2 (A + B + C)'s 1 day's work =¬(1/18 + 1/24 + 1/36)   =9/72 =1/8   (A +B + C)'s 1 day's work =1/16   Thus, A, Band C together can finish the work in 16 days.   Ans: 16 days

P and Q started a business with respective investments of Rs. 4 lakhs and Rs. 10 lakhs. As P runs the business, his salary is Rs. 5000 per month. If they earned a profit of Rs. 2 lakhs at the end of the year, then find the ratio of their earnings?  Choices
A) 1:5
B) 1:0
C) 1:3
D) 1:1
E) 1:2

Solution: Ratio of investments of P and Q is 2 : 5   Total salary claimed by P = 12 * 5000 = Rs. 60000   Total profit = Rs. 2 lakhs.   Profit is to be shared = Rs. 140000   Share of P = (2/7) * 140000 = Rs. 400000   Share of Q = Rs. 100000   Total earnings of P = (60000 + 40000) = Rs. 100000   Ratio of their earnings =1:1   Answer: 1:1

The distance between two cities A and B is 330 km. A train starts from A at 8 a.m. and travel towards B at 60 km/hr. Another train starts from B at 9 a.m. and travels towards A at 75 Km/hr. At what time will they meet? Choose the correct choice from the following answers:  A) 10  B) 07  C) 08  D) 11  E) 04

Solution: Explanation :   Assume that they meet x hours after 8 a.m.   Then, train1,starting from A , travelling towards B, travels x hours till the trains meet   ⇒Distance travelled by train1 in x hours = Speed ×Time = 60x   Then, train2, starting from B , travelling towards A, travels (x-1) hours till the trains meet   ⇒Distance travelled by train2 in (x-1) hours = Speed ×Time = 75(x-1)   Total distance travelled = Distance travelled by train1 + Distance travelled by train2   => 330 = 60x + 75(x-1)   => 12x + 15(x-1) = 66   => 12x + 15x - 15 = 66   => 27x = 66 + 15= 
66 + 15 = 81
81=> 3x = 9   => x = 3   Hence the trains meet 3 hours after 8 a.m., i.e. at 11 a.m.   Answer : 11

What was the day of the week on 17th June 1998?  Select
A) Monday  B) Sunday  C) Wednesday  D) Friday  E) None of these

Solution: Explanation :   17 Jun 1998 = (1997 years + period from 1-Jan-1998 to 17-Jun-1998)   We know that number of odd days in 400 years = 0   Hence the number of odd days in 1600 years = 0 (Since 1600 is a perfect multiple of 400)   Number of odd days in the period 1601-1900   = Number of odd days in 300 years   = 5 x 3 = 15 = 1   (As we can reduce perfect multiples of 7 from odd days without affecting anything)   Number of odd days in the period 1901-1997   = 73 normal years + 24 leap year   = 73 x 1 + 24 x 2 = 73 + 48= 
73 + 48 = 121
121= (121 - 7 x 17) = 2 odd days   Number of days from 1-Jan-1998 to 17-Jun-1998   = 31 (Jan) + 28 (Feb) + 31 (Mar) + 30 (Apr) + 31(may) + 17(Jun)   = 168 = 0 odd day   Total number of odd days = (0 + 1 + 2 + 0)= 
(0 + 1 + 2 + 0) = 3
3   3 odd days= Wednesday   Hence 17th June 1998 is Wednesday. Answer : Option Wednesday

In a fuel station the service costs $2.20 per vehicle and every liter of fuel costs $0.70. Assuming that you fill up 4 mini-vans and 2 trucks, what will be the total cost, if a mini-van's tank is 65 liters and a truck's tank is 120% bigger and they are all empty?	Choose the correct choice from the following answers:
A) $382.10 B) $395.40 C) $404.30 D) $416.80 E) $426.50

Solution: The service cost of 4 vans and 2 trucks is 6*2.20 $13.20   The fuel in 4 vans is 4*65= 
4*65 = 260
260 liters   The fuel in 2 trucks is   2*65*2.2= 
  2*65*2.2 = 286
286 liters   The total fuel (vans + trucks)= 546 liters   The total fuel cost is 546*0.7= 
546*0.7 = 382.2
$382.20   The total cost is $382.20 + $13.20 = $395.40   The answer is $395.40. 382.20 +  13.20= 
 382.20 +  13.20 = 395.4
$395.40   The answer is $395.40.

Choose one.
A) 1  B) 2  C) 5  D) 6  E) 14

Solution: Try with the options -   A. If BC = 1 , both B and C must be 1   B. If BC = 2 , either B or C must be 1 or 2 ; In that case sum of the digits will be 8 + 1 + 2=

11 which is not divisible by 3   C. If BC= 5 , either B or C must be 1 or 5 ; In that case sum of the digits will be 8 + 1 + 5= 
8 + 1 + 5 = 14
14 which is not divisible by 3   D. If BC= 6 , then we can have the following possibilities   i. Either B or C must be 2 or 3 ; In that case sum of the digits will be 8 + 2 + 3= 
8 + 2 + 3 = 13
13 which is not divisible by 3   ii. Either B or C must be 1 or 6 ; In that case sum of the digits will be 8 + 1 + 6= 
8 + 1 + 6 = 15
15 which is divisible by 3   E. If BC= 14 , then either B or C must be 2 or 7 ; In that case sum of the digits will be 8 + 2 + 7=

If f(x) = 12 - x^2/2 and f(2k) = 3k, what is one possible value for k? Pick one:
A) 2 B) 3 C) 4 D) 6 E) 8

Solution: First of all, see thisGMAT blog postand check the related lesson linked below for some background on function notation.   We can plug anything in for x and get a result. You can find f(1), for example, by plugging in 1 where x is, and you would get 12 - 1/2 = 11.5. Or we could find f(2), which would be  12 - 4/2= 
 12 - 4/2 = 10
10.   So the notation f(2k) means that we are going to plug a 2k in for x everywhere in the formula for f(x). That would be:   f(2k)= 12 - (2k)^2/2 = 12 - 2k^2.   Remember that we have to square both the 2 and the k, to get 4k2. Now, this expression, the output, we will set equal to 2k.   12 - 2k^2 = 2k --> k = -4 or k = 3.   All the answers are positive, so we choose k = 3.   Answer = 3

If n is an integer, then the least possible value of |15 - 8n| is?	Pick.
A) 0	B) 2	C) 1	D) 3	E) 5

Solution: |15 - 8n| represents the distance between 15 and 8n on the number line. Now, the distance will be minimized when 8n, which is multiple of 8, is closest to 15. Multiple of 8 which is closest to 15 is 16 (for n = 2), so the least distance is 1: |15 - 16| = 1.   Answer: 1.
Answer: C
