let one no. be 7x
then the other nos. will be 7(x+1) and 7(x+2)
A/Q
x+ 7x+7+ 7x+14= 777
15x+21 = 777
15x = 777-21
15x= 756
x= 756/15
x=252/5
then the other nos. will be 7(x+1) and 7(x+2)
A/Q
x+ 7x+7+ 7x+14= 777
15x+21 = 777
15x = 777-21
15x= 756
x= 756/15
x=252/5
skthegreat:
the solution is wrong
as the question is asking consecutive multiples not just the consecutive sum
I guess this one is also wrong
I'm sorry
Ok but practice it
you will be the best

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
