Let the C.P of each camera be Rs. X.

C.P of 15 chocolates = 15x

Profit = 30/100 × 15x = 45x/10

C.P of 10 chocolates = 10x

Profit = 10/100 × 10x = 10x/10

C.P of 25 chocolates = 25x

Overall profit = 20/100 × 25x = 50x/10

50x/10 = (45x/10 + 10x/10) – 44

5x = 55x/10 – 44

44 = 5.5x – 5x

44 = 0.5x

X = 88
