General Aptitude Question on Time and Work
Aman can do 50% of the job in 16 days, and Bhanu can do 25% of the job in 24 days. In how many days can they do 1/4 of the job working together?
A
6 days
B
8 days
C
10 days
D
12 days
Answer
8 days
Explanation
Solution
Aman can complete the whole job in 16 × 2 = 32 days. Bhanu can complete the job in 24 × 4 = 96 days. Their combined work rate is 1/32 + 1/96 = 4/96 = 1/24 of the job per day. Therefore, 1/4 of the job will take 24 × 1/4 = 8 days.
