14 men complete a work in 10 days. If 7 men are employed, then in how many days will they complete the same work?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 20.
Total work = Total men working × Total time required
Total work = 14 × 10 = 140 units
Time required by 7 men to complete the work = 140/7 = 20 days
