Question

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

Answer 1

7x+7x+7+7x+14=777
so x=777-21/21
x=36
252,259,266 is answer

Answer 2

Answer:

let the three consecutive multiples be x

1st multiples =x

2nd multiples =x+7

3rd multiples =x+14

a.t.q.

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

=> 3x+21=777

=> 3x=777−21

=> 3x=756

=> x=756/3

=> x=252

1st multiples =x=252

2nd multiples =x+7=252+7=259

3rd multiples = x+14=252+14=266answer
