Problem: a not - so - good clockmaker has four clocks on display in the window . clock # 1 loses 45 minutes every hour . clock # 2 gains 15 minutes every hour relative to clock # 1 ( i . e . , as clock # 1 moves from 12 : 00 to 1 : 00 , clock # 2 moves from 12 : 00 to 1 : 15 ) . clock # 3 loses 20 minutes every hour relative to clock # 2 . finally , clock # 4 gains 20 minutes every hour relative to clock # 3 . if the clockmaker resets all four clocks to the correct time at 12 noon , what time will clock # 4 display after 6 actual hours ( when it is actually 6 : 00 pm that same day ) ?
Options: a ) 5 : 00 , b ) 5 : 34 , c ) 5 : 42 , d ) 6 : 34 , e ) 6 : 24
Rationale: "c 1 loses 15 minutes every hour . so after 60 minutes have passed , c 1 displays that 60 - 15 = 45 minutes have passed . c 2 gains 15 minutes for every 60 minutes displayed on c 1 . thus , the time displayed on c 2 is 75 / 60 = 5 / 4 the time displayed on c 1 . so after 60 minutes have passed , c 2 displays the passing of ( 5 / 4 * 45 ) minutes . c 3 loses 20 minutes for every 60 minutes displayed on c 2 . thus , the time displayed on c 3 is 40 / 60 = 2 / 3 the time displayed on c 2 . so after 60 minutes have passed , c 3 displays the passing of ( 2 / 3 * 5 / 4 * 45 ) minutes . c 4 gains 20 minutes for every 60 minutes displayed on c 3 . thus , the time displayed on c 4 is 80 / 60 = 4 / 3 the time displayed on clock 3 . so after 60 minutes have passed , c 4 displays the passing of 4 / 3 * 2 / 3 * 5 / 4 * 45 = 50 minutes . c 4 loses 10 minutes every hour . in 6 hours , c 4 will lose 6 * 10 = 60 minutes = 1 hour . since the correct time after 6 hours will be 6 pm , c 4 will show a time of 6 - 1 = 6 : 34 pm . the correct answer is d ."

Rationale: "a can finish 1 work in 20 days b can finish 1 / 2 work in 20 days - since a is 2 faster than b this means b can finish 1 work in 20 * 2 days = 40 days now using the awesome gmat formula when two machines work together they can finish the job in = ab / ( a + b ) = 20 * 40 / ( 20 + 40 ) = 13 days since they alternate on days , it will take them double this time so total time = 13 * 2 = 26 days so answer is e"
Answer: e
Python program:
a = 1 / 20
b = 1 / 20
c = b / 2
d = a + c 
e = 1 / d

Problem: what is the greatest integer m for which the number 30 ! / 10 ^ m is an integer ?
Options: a ) 7 , b ) 8 , c ) 9 , d ) 10 , e ) 11
Rationale: "10 ^ m = 2 ^ m * 5 ^ m . let ' s figure out how many 5 ' s are in the prime factorization of 30 ! the multiples of 5 are : 5 , 10 , 15 , 20 , 5 * 5 , 30 . thus 5 ^ 7 will divide 30 ! but 5 ^ 8 will not . clearly 2 ^ 7 will divide 30 ! so m = 7 is the largest possible integer . the answer is a ."
Answer: a
Python program:
a = 10 / 2

Problem: the speed at which a man can row a boat in still water is 20 kmph . if he rows downstream , where the speed of current is 4 kmph , what time will he take to cover 80 metres ?
Options: a ) 10.51 , b ) 11.51 , c ) 9.51 , d ) 13.51 , e ) 15.51
Rationale: speed of the boat downstream = 20 + 4 = 24 kmph = 24 * 5 / 18 = 6.66 m / s hence time taken to cover 70 m = 70 / 6.66 = 10.51 seconds . answer : a
Answer: a
Python program:
a = 20 + 4 
b = a * const_0_2778

Problem: the sides of a triangle are in the ratio 5 : 12 : 13 and its perimeter is 360 m , its area is ?
Options: a ) 180 , b ) 882 , c ) 277 , d ) 261 , e ) 281
Rationale: "5 x + 12 x + 13 x = 360 = > x = 12 a = 60 , b = 144 , c = 156 s = ( 60 + 144 + 156 ) / 2 = 180 answer : a"
Answer: a
Python program:
a = 5 + 12 
b = a + 13 
c = 360 / b
d = 360 * c
Problem: the cost of 2 chairs and 3 tables is rs . 1800 . the cost of 3 chairs and 2 tables is rs . 1200 . the cost of each table is more than that of each chair by ?
Options: a ) 228 , b ) 287 , c ) 277 , d ) 188 , e ) 600
Rationale: "explanation : 2 c + 3 t = 1800 - - - ( 1 ) 3 c + 3 t = 1200 - - - ( 2 ) subtracting 2 nd from 1 st , we get - c + t = 600 = > t - c = 600 answer : e"

Problem: jim is able to sell a hand - carved statue for $ 670 which was a 35 % profit over his cost . how much did the statue originally cost him ?
Options: a ) $ 496.30 , b ) $ 512.40 , c ) $ 555.40 , d ) $ 574.90 , e ) $ 588.20
Rationale: "670 is the final price that is the selling price . now suppose , x is the cost price . therefore 670 = 1.35 * x now while doing x = 670 / 1.35 calculation . i saw that the answer choices begin with 5 . so i did 135 * 5 = 675 . as 670 is less than 675 . therefore the quotient will be less than 5 . which is only in the answer a ."
Answer: a
Python program:
a = 35 / 100
b = a + 1 
c = 670 / b
Problem: a baseball team played 10 games and won 5 . what is the ratio of the number of games played to the number of losses ?
Options: a ) 5 : 1 , b ) 1 : 1 , c ) 20 : 4 , d ) 10 : 3 , e ) 2 : 1
Rationale: the number of games played is 10 . the number of games won is 5 , so 10 - 5 = 5 = number of game losses . answer = ! 0 : 5 = 2 : 1 answer is e

Problem: 3 buffaloes eat as much as 4 cows or 2 oxen . at a farm , there are 15 buffaloes , 8 oxen , and 24 cows . the fodder for these cattle is available for 48 days . if 40 more cows and 15 more buffaloes are brought in , how many days will the fodder last ?
Options: a ) 20 , b ) 24 , c ) 28 , d ) 32 , e ) 36
Rationale: "2 oxen = 3 buffaloes = 4 cows also : 15 buffaloes + 8 oxen + 24 cows = 10 oxen + 8 oxen + 12 oxen = 30 oxen there is enough fodder for 1 oxen for 30 * 48 days . 40 cows + 15 buffaloes = 20 oxen + 10 oxen = 30 oxen the new total is equal to 60 oxen instead of 30 oxen . 30 * 48 / 60 oxen = 24 days the answer is b ."
