Running 3/4th of his usual rate, a man is 12min late. Find his usual time in hours ? | [
"3/5 hrs",
"3/4 hrs",
"6/4 hrs",
"1/4 hrs"
] | A | Explanation:
Walking at 3/4th of usual rate implies that time taken would be 4/3th of the usual time. In other words, the time taken is 1/3rd more than his usual time
so 1/3rd of the usual time = 12min
or usual time = 3 x 12 = 36min = 36/60 hrs = 3/5 hrs.

On Monday, a certain animal shelter housed 72 cats and dogs. By Friday, 1/6 of the cats and 1/5 of the dogs had been adopted; no new cats or dogs were brought to the shelter during this period. What is the greatest possible number of pets that could have been adopted from the animal shelter between Monday and Friday? | [
"12",
"14",
"15",
"11"
] | B | To maximize the number of pets adopted, we should maximize the number of dogs adopted since 1/5 > 1/6.
The greatest multiple of 5 less than 72 is 60 (such that the remaining number is divisible by 6), so let's assume there were 60 dogs and 12 cats.
Then the maximum number of adopted pets is 1/5*(60) + 1/6*(12) = 12 + 2... | AquaRat_train |

Average expenditure of a person for the first 3 days of a week is Rs. 360 and for the next 4 days is Rs. 420. Average expenditure of the man for the whole week is: | [
"370",
"None",
"390",
"400"
] | D | Explanation:
Assumed mean = Rs. 360
Total excess than assumed mean = 4 × (Rs. 420 - Rs. 350) = Rs. 280
Therefore, Increase in average expenditure = Rs. 280/7 = Rs. 40
Therefore, Average expenditure for 7 days = Rs. 360 + Rs. 40 = Rs. 400

P and Q can complete a work in 10 days and 6 days respectively. P alone started the work and Q joined him after 2 days till the completion of the work. How long did the work last? | [
"14 days",
"5 days",
"10 days",
"26 days"
] | B | Explanation :
Work done by P in 1 day = 1/10
Work done by Q in 1 day = 1/6
Work done by P in 2 days = 2 × (1/10) = 1/5
Remaining work = 1 – 1/5 = 4/5
Work done by P and Q in 1 day = 1/10 + 1/6 = 4/15
Number of days P and Q take to complete the remaining work = (4/5) / (4/15) = 3
Total days = 2 + 3 = 5
