Question

If30is added to the twice of a number it becomes the five times of the number .what is the number?​

Answer 1

Let the number be ‘x’


According to the question

30+2x=5x

30=5x-2x

30=3x

x=10

Answer 2

Let, the number be, 'x'

Twice of x =2x

Adding 30 with '2x'=(2x+30)

5 times of x =5x

By condition,

$5x=2x+30\\⇒5x-2x=30\\⇒3x=30\\⇒x=30/3\\⇒x=10$

∴ The number is $10$
