Answer» Answer: B) 24 hours. Step-by-step explanation: John stitches a TROUSER in 4 hours => John stitches 1/4 of a trouser in 1 hour. Jack stitches a trouser in 3 hours => Jack stitches 1/3 of a trouser in 1 hour. So, both WOULD STITCH 1/4 + 1/3 = 3/12 + 4/12 = 7/12 of a trouser in 1 hour. If they both have to stitch 14 trousers together, it would take (14 ÷ 7/12) hours = (14 × 12/7) hours = 24 hours. |
