Question

a number is fourtimes another number .if the large number is 10 more than twice the smaller no. find the two numbers

Answer 1

let one number be x.
then other number be 4x.

so, the large number is 4x.
ATQ
4x=2x+10.
4x-2x=10.
2x=10.
x=10/2
x=5.

small number is 5.
and the large number is 4×5=20.
