If 20 men can build a water fountain 56 metres long in 3 days, what length of a similar water fountain can be built by 35 men in 3 days? | [
"64 m",
"77 m",
"40 m",
"98 m"
] | D | Explanation :
Let the required length be x metres
More men, More length built (Direct Proportion)
Less days, Less length built (Direct Proportion)
Men 20: 35
Days 3: 3 : : 56 : x
Therefore (20 x 3 x x)=(35 x 3 x 56)
x=(35 x 3 x 56)/60=98
Hence, the required length is 98 m.

w is not divisible by 2, thus 2 goes to n
n is not divisible by 3, thus 3 goes to w.
From above:
n must be divisible by 2 and not divisible by 3: n = 2*... In order n to be a 3-digit number it must take all other primes too: n = 2*5*23 = 230.

John started driving on a highway at a constant speed of R miles per hour at 13:00. Then, 2 hours later, Tom started driving on the same highway at a constant speed of 6R/5 miles per hour at 15:00. If both drivers maintained their speed, how many miles had John driven on the highway when Tom caught up with John? | [
"12R",
"6R",
"10R",
"9R"
] | A | In 2 hours, John drove 2R miles.
Tom can catch John at a rate of 6R/5 - R = R/5 miles per hour.
The time it takes Tom to catch John is 2R / (R/5) = 10 hours.
In 10 hours, John can drive another 10R miles for a total of 12R miles.

Based on this year's costs, a factory budgets P dollars for planing N new cars next year. If the average cost of building each car were to increase 50% from this year's cost, then the greatest number of cars that the factory could build next year using P dollars would be: | [
"33% greater than N",
"67% less than N",
"Equal to N",
"33% less than N"
] | D | Correct answer is (A).
This year, the price of a car is price1=P/N.
If this price increases by 50% it becomes Price2=P/N*1.5
Then with P dollars, you can build P/Price2 cars i.e. P/(P/N*1.5) i.e. N/1.5 i.e. 0.67*N
Which is 33% less than N. | AquaRat_train |

"10.15%",
"10.25%",
"30.25%",
"10.28%"
] | B | Let the sum be Rs. 100. Then,
S.I. for first 6 months = (100 * 10 *1) / (100 * 2) = Rs. 5
S.I. for last 6 months = (105 * 10 * 1) / (100 * 2) = Rs. 5.25
So, amount at the end of 1 year = (100 + 5 + 5.25) = Rs. 110.25
Effective rate = (110.25 - 100) = 10.25%.

And
(20*5 + 12*3) - (20*5*(1-B) + 12*3*(1-M)) = 19
