Question

A number is 5 times another number. If 12 is added to both the numbers,then the new numbers formed becomes thrice the other new number. Find the numbers​

Answer 1

Answer:

Let another number be x.

Then positive number = 5x

According to the question, 5x+21=2\left(x+21\right)

\Rightarrow5x+21=2x+42

\Rightarrow5x-2x=42-21

\Rightarrow3x=21

\Rightarrow x=\frac{21}{3}=7

Hence another number = 7 and positive number = 7 x 5 = 35.
