Question

Sum of three consetutive numberof 7 is 777 find the multiples

Answer 1

Answer:

Let the firstconsecutive multiple of 7 be x

Then, second consecutive multiple of 7 is x + 7

& 3rd consecutive multiple of 7 is x + 7 + 7 = x+14

according to the question,

x + x+ 7 + x + 14 = 777

or, 3x = 777 - 21

or, 3x = 756

or, x = 756/3

x = 252

Therefore, the first multiple of 7 = x = 252

second multiple of 7=x+7=252+7 = 259

third multiple of 7=x+14=252+14=266

Check out for this answer

Step-by-step explanation:

let us take three consecutive multiples of that are x,x+7,x+14

Now according to question,\

     x+(x+7)+(x+14)=777

     3 x + 21 = 777

     3 x =777-21

     3 x = 756

        x = 756/3

         x = 252

Now , The  three consecutive multiples of 7 whose sum will be 777 are,

x=252

x+7=252+7 =259

x+14= 252+14=266

henceforth the required numbers are 252,259 and 266.
