Pardeep can complete a piece of work in 16 days. He worked for 4 days and left the work, thereafter Sohan finished the remaining work in 8 days. In how many days, can Pardeep and Sohan together complete the work?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. .
Pardeep's rate = 1/16
Work done by Pardeep in 4 days = 4(1/16) = 1/4
Remaining work = 1 - 1/4 = 3/4
Sohan's rate = (3/4)/8 = 3/32
Combined rate = 1/16 + 3/32 = 5/32
Time required = 32/5 = days
