HELLO MATE ,,❤❤❤

Answer:

12 and 6 years old..

Step-by-step explanation:

Let,

The present age of Tahir be Y..

The present age of Masood be X..

According to question,

X + Y = 18 ----------Eq.1

Y - 3 = 3(X - 3)

Y - 3 = 3X - 9

3X - Y = 6 --------Eq.2

From 1 ,

X = 18 - Y

Substitute X value in Eq.2

3(18 - Y) - Y = 6

54 - 3Y - Y = 6

54 - 4Y = 6

4Y = 54 - 6

4Y = 48

Y = 12..

Substitute Y value in Eq.1

X + 12 = 18

X = 18 - 12

X = 6..

Therefore,

Present age of Tahir is 12 years..

Present age of Masood is 6 years..

Hope It Helps You !!!
