Question

two numbers are multiplied and their product obtained is 42.if both the numbers are doubled , and ten multiplied, what will be there product?

Answer 1

Hey!!!!

let the numbers be x and y.

Then

=> xy = 42

Also

If we now double the numbers and multiply that by 10, the product will also be changed.

Thus

$42 \times 2 \times 2 \times 10 = 1680$

Thus the new product will be 1680.

Hope this helps
