Answer 1

HEY MATE,
Here is your answer
___________________________

• Let one number( out of other numbers 2) be $\bf\mathbb{x}$
• So, the second number ( out of other 2 numbers) be $\bf\mathbb{x\:+\:20}$
• Third numbers is 195.
• Mean of these numbers = 135

A.T.Q,

$= > \frac{x + x - 20 + 195}{3} = 135 \\ = > 2x + 175 = 135 \times 3 \\ = > 2x = 405 - 175 \\ = > 2x = 230 \\ = > x = \frac{230}{2} \\ = > x = 115 \\ So, \: x - 20 = 95$

So, the other 2 numbers are 95 and 115.
