Maya completes 7/10 of a work in 15 days and then she completes the remaining work with the help of Suresh in 4 days. In how many days can Maya and Suresh complete the whole work?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. .
Maya's rate = (7/10)/15 = 7/150
Remaining work = 3/10
Combined rate (Maya + Suresh) = (3/10)/4 = 3/40
Time for whole work = 1/(3/40) = 40/3 days
