Question

The sum of threee consecutive multiples of 7 is 357 . Find yhe smallest multiple

Answer 1

Let 1 St multiple = 7x

2 nd multiple = 7x+7

3 Rd multiple = 7x +14

Then,

ATQ :

7x+7x+7+7x+14 = 357

21x+21 = 357

21x = 357-21

21x = 336

x = 336/21 = 16

Smallest multiple = 7x = 7×16 = 112.

The smallest multiple is = 112
