A can do 50% of job in 16 days, B can do 1/4th of the job in 24 days. In how many days can they do 3/4th of the job working together?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 ie 18.
A can complete the whole work in = 16 × 2 = 32 days
B can complete the whole work in = 24 × 4 = 96 days
They both can complete the whole work in = (96 × 32)/128 = 24 days
They can complete 3/4th work in = 24 × (3/4) = 18 days
