Question

the product of two numbers is 7260 if one number is 15 times the other number find the numbers

Answer 1

Let the first number be x.
So the another number will be 15x.

According to question:-
x × 15x = 7260
15x^2 = 7260
x^2 = 7260/15
x^2 = 484
x = √484
x = 22.

So the numbers are:-
x = 22
&
15x = 15×22
= 330

Hope it helps.

Answer 2

let the 1st number be ,x
then 2nd number be 15x
since, product of two number 
therefor,x*15x=15xsqure
so,xsqure=7260/15
xsqure=484
so,x=22 and 15x=15*22=330
