Question 1
Q1. If 12 carpenters, working 6 hours a day, can make 460 chairs in 24 days, how many chairs
will 18 carpenters make in 36 days, each working 8 hours a day ?
Answer : 1380
Let the required number of chairs be x . Then ,
∴ 12 × 6 × 24 × x = 18 × 8 × 36 × 460
⇒ x = (18 × 8 × 36 × 460)/(12 × 6 × 24) = 1380
Hence, the required number of chairs is 1380.
