Let the present age be= x
Therefore, his age 3yrs later =x+3
so, 3(x+3)
minus 3 times of what was 3 yrs ago= 3(x-3)
Therefore, 3(x+3)-3(x-3)
=3x+9-3x+9
+3x and -3x gets cancelled, therefore, 9+9 =18
Ans=18yrs

His present age be x
His age after 3 yrs =x+3
so 3[x+3]
hence 3[x+3]-3[x-3]
= 3x-3x+9+9
=18
so answer is 18 years
