Question 1
Q1. 15 men take 21 days of 8 hours each to do a piece of work. How many days of 6 hours each would 21 women take, if 3 women do as much work as 2 men ?
Answer : 30
3 women ≡ 2 men
So, 21 women ≡ 14 men .
Let the required number of days be x. Then ,
∴ 14 × 6 × x = 15 × 8 × 21
⇒ x = (15 × 8 × 21)/(14 × 6) = 30
Hence, the required number of days is 30.
