20 sparrows = 1 Re, that means each sparrow is of 0.05 Re.
• So, let's take 80 sparrows which costs 4 Rs. (80 * 0.05)
• Now take 19 pigeons which costs 95 Rs. ( 19*5).
• Finally take 1 parrot which costs 1 Re. ( 1*1)
80 sparrows + 19 pigeons + 1 parrot = 100 Birds.
4 + 95 + 1= 100/-
Hence proved 100 Birds at 100 Rs.
