Sonu alone can make a table in 125 days while Monu alone can make it in 250 days. Monu started the work and worked for 75 days. In how many days Somu can finish the remaining work?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 87.5 days.
Sonu alone can make a table in 125 days while Monu alone can make it in 250 days
L.C.M(125, and 250) = 250
The efficiency of Sonu = 250/125 = 2 days
The efficiency of Monu = 250/250 = 1 day
Monu started the work and worked for 75 days then
Work done by Monu = 75 × 1 = 75 units
Remaining work = 250 - 75 = 175 units
Time taken by Sonu = 175/2 = 87.5 days
