Question

the sum of three consecutive multiplesof 7 is 777. find this multiple

Answer 1

let consecutive no. be 7x ,7x+7 and 7x+14
now it is given ...
7x+7x+7+7x+14 = 777
21x+21 = 777
21x= 777-21
21x = 756
x= 756/21 = 36
now put the value of x in 7x ,7x+7and 7x+14
u will get multiples.....

Answer 2

Here is your answer

Let,
The three consecutive multiples of 7 be 7x, 7x + 7 and 7x + 14.

7x + (7x + 7) + (7x + 14) = 777 (Given)

⇒21x + 21 = 777

⇒ 21x = 777 – 21

⇒ 21x = 756

⇒ x = 36


Number are:-

7x=7×36=252

7x + 7 = 252 + 7 = 259

7x + 14 = 252 + 14= 266


Hence,

The three consecutive multiples of 7 are 252, 259 and 266

Hope it helps you
