35 girls can complete a piece of work in 12 days. If 5 fewer girls are put on the work, in how many days can they complete the work?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 14 days.
Explanation :
Given that, 35 girls can do the work in 12 days.
Hence the total work done by 35 girls in 12 days = 35 × 12 = 420
Now this work is completed by 30 girls in 420/30 = 14 days.
Hence 30 girls can complete the work in 14 days.
