the difference between two number is 642. when the greater is divided by smaller the quotient is 8 and the remainder is 19, then find the sum of cube of numbers

Step-by-step explanation:

GIven that,

Dividend is greater than Divisor by 642.

Therfore, let,

Dividend = x + 642.

Divisor = x

Quotient = 8

Remainder = 19.

We know that, Dividend = Divisor * Quotient + Remainder.

Therefore, x+642 + X. 8 + 19.

X + 642 = 8X + 19.

642 - 19 = 8X - X

7X = 623

X = 623/7

X = 89.

Therefore, Divisor = 89

Dividend = X+642=731.
