Given:
Ratio of Boys and Girls = 7:8

Percentage increase in the number of boys = 20%
Percentage increase in the number of girls = 10%

Let the initial number of boys and girls be 7x and 8x respectively.

After the percentage increase, the number of boys and girls will become:
New number of boys = 120% of 7x = (120/100)*7x = 8.4x
New number of girls = 110% of 8x = (110/100)*8x = 8.8x

The new ratio will be:
8.4x : 8.8x
Simplifying by dividing both the numbers by 0.4x, we get:
21 : 22

Hence, the new ratio of boys and girls in the college is 21:22.

Therefore, the correct answer is option (C) 21:22.
