= 80 - (amar3 + akbar3 + anthony3).

= 80 - 9.

= 71.

Every year each ones age will increase by 1 therefore together it would be 1+1+1 = 3, (Amar + Akbar + Anthony's total age grew by= 3 years in one year).

Now what would be the total increment in their age in 3 years, i.e., 3x3=9.

9 years is how. Much all the 3 of them together grew, so minus 9 from 80 which is their present total age.

= 71.

= 80 - (amar3+akbar3+anthony3).

= 80 - (9 their ages).

= 71.

See there are 3 person so 3 we've to take then multiple 3 with that 3 person it'll come 9

So 80-3x3=71
