Answer 2

Hello Dear!!!

Here's your answer....

Given that,

Product of two numbers is 15876.

One number is 9 times the other.

Let,

one number be x

other number is 9 times x = 9x

Product is 15876

9x * x = 15876

9x^2 = 15876

x^2 = 15876/9

x^2 = 1764

x = √1764

x = 42

Other number is 9 times...

9(42)

378

sum is

378+42

420

answer is 420
