Find the cost of each book

Solution:

3 maths + 4 science books = Rs.216

Cost of 3 maths books = cost of 4 science books

Hence their cost = $\frac{216}{2}$= 108.

Cost of 3 maths books = Rs.108

1 maths book = $\frac{108}{3}$ = Rs.36

Cost of 4 science books = Rs.108

1 science book = $\frac{108}{4}$ = Rs.27
