Question

the sum of three consecutive multiples of 7 is 777.find these multiples

Answer 1

Hii
Here is Your answer
_______________________________________________________

Ist consecutive multiple of 7 = x
IInd consecutive multiple of 7 = x + 7
IIIrd consecutive multiple of 7 = x + 14

A.T.Q

=> x + x + 7 + x + 14 = 777
=> 3x + 21 = 777
=> 3x = 777 - 21
=> 3x = 756
=> x = 756/3
=> x = 252

Hence, Ist consecutive multiples of 7 = x
= 252

IInd consecutive multiple of 7 = x + 7
= 252 + 7
= 259

IIIrd consecutive multiple of 7 = x + 14
= 252 + 14
= 266

Answer 2

Constitutive multiples of 7 = x,x+7,x+14

= x + x+7 + x+14 = 777

= 3x + 21 = 777

= 3x = 777-21

= 3x = 756

= x= 756/3 = 252...

So therefore, x=252

x+7=259

x+14=266

So the consecutive multiples are 252,259,266.
