Question

Two numbers are in the ratio 5:3 and their difference is 10. What is the product of two numbers?

Answer 1

Let the numbers be 5x and 3x.
⇒By the condition
$5x-3x=10$
⇒$2x=10$
⇒$x= \frac{10}{2}$
⇒$x=5$
⇒The numbers are 5*5=25 and 3*5=15
⇒Their product=$5x*3x=15x^2$
=15*25 = 375
Ans:Their product is 375.

Answer 2

The numbers are 25 and 15
diff 25-15 = 10
product 25*15 = 375
