A train passes a station platform in 36 seconds and a man standing on the platform in 20 seconds. If the speed of the train is 54 km/hr, what is the length of the platform? | [
"161",
"240",
"299",
"921"
] | B | Speed = (54 * 5/18) m/sec = 15 m/sec. Length of the train = (15 x 20)m = 300 m. Let the length of the platform be x meters. Then, (x + 300)/36 = 15
==> x + 300 = 540 ==> x
= 240 m.

A committee is reviewing a total of 40x black-and-white films and 4y color films for a festival. If the committee selects y/x% of the black-and-white films and all of the color films, what fraction of the selected films are in color? | [
"10/11",
"20/11",
"16/11",
"17/11"
] | A | Say x=y=10. In this case we would have:
40x=200 black-and-white films;
4y=40 color films.
y/x%=10/10%=1% of the black-and-white films, so 4 black-and-white films and all 40 color films, thus total of 44 films were selected.
Color films thus compose 40/44=10/11 of the selected films.

"12, 11 and 6",
"12, 6 and 11",
"6, 11 and 12"
] | C | M = 2P
L = P+5
M + P + L = 29
2P + P + (P+5) = 29
P = 6, M = 12, L = 11
Therefore, Mary, Peter, and Lucy picked 12, 6, and 11 kg, respectively.

Kiran travels from A to B by car and returns from B to A by cycle in 7 hours. If he travels both ways by car he saves 3 hours. What is the time taken to cover both ways by cycle? | [
"16 hours",
"17 hours",
"10 hours",
"27 hours"
] | C | Let the time taken to cover from A to B in car and cycle be x hours and y hours respectively.
x + y = 7 --- (1) ; 2x = 4 --- (2)
solving both the equations, we get y = 5
So, time taken to cover both ways by cycle = 2y hours = 10 hours.

P and Q can complete a work in 40 days and 24 days respectively. P alone started the work and Q joined him after 8 days till the completion of the work. How long did the work last? | [
"20 days",
"5 days",
"26 days",
"14 days"
] | A | Explanation :
Work done by P in 1 day = 1/40
Work done by Q in 1 day = 1/24
Work done by P in 8 days = 8 × (1/40) = 1/5
Remaining work = 1 – 1/5 = 4/5
Work done by P and Q in 1 day = 1/40 + 1/24 = 1/15
Number of days P and Q take to complete the remaining work = (4/5) / (1/15) = 12
Total days = 8 + 12 = 20

A motorcycle importer is planning on increasing the price of a certain model by $1000. At this new price 7 fewer motorcycles will be sold per month, but the total revenues will increase by $26,000 to $594,000. What is the number of motorcycles the manufacturer will sell at this new price? | [
"64",
"65",

] | A | I will make an equation in x and then make educated guesses. Here's how:
Assuming x motorcycles were sold every month initially.
(568000/x + 1000)(x-7) = 594000
(568/x + 1)(x-7) = 594
Now 568 = 8*71
Assuming x = 71 (We have all integers so it is obvious that 568/x should be an integer.

In a 1000 m race, A beats B by 50 m and B beats C by 100 m. In the same race, by how many meters does A beat C? | [
"218 m",
"268 m",
"176 m",
"145 m"
] | D | By the time A covers 1000 m, B covers (1000 - 50) = 950 m.
By the time B covers 1000 m, C covers (1000 - 100) = 900 m.
So, the ratio of speeds of A and C =
1000/950 * 1000/900 = 1000/855 So, by the time A covers 1000 m, C covers 855 m.
So in 1000 m race A beats C by 1000 - 855 = 145 m.

=> (90%) of (110%) of x = Rs. 2178.
=> (90/100)(110/100)x = 2178
=> x = (2178 * 100)/(9 * 11)

] | D | Explanation:
A runs 1000 meters while B runs 900 meters and C runs 830 meters.
Therefore, B runs 900 meters while C runs 830 meters.
So, the number of meters that C runs when B runs 1000 meters = (1000 x 830)/900 = 922.22 meters
Thus, B can give C (1000 - 922.22) = 77.77 meters start
