Question

Two brands of chocolates are available in packs of 24 and 15 respectively. If I need to buy an equal number of chocolates of both kinds, what is the least number of boxes of each kind I would need to buy?

Answer 1

Number of chocolates of 1st brand in one pack = 24

Number of chocolates of 2nd brand in one pack = 15

∴ The least number of chocolates I need to purchase

= LCM of 24 and 15

= 2 × 2 × 2 × 3 × 5

= 120

∴ The number of packet of 1st brand `=120/24=5`

All the number of packet of 2nd brand `120/15=8`
