Question

There are peacocks and deers in a park. If the total number of their heads is 150 and that of legs is 400, what is the number of deer?

Answer 1

Answer: There are 50 deer in the park.

Step-by-step explanation: 50 deer x 4 legs per deer = 200 legs

100 peacocks x 2 legs per peacock = 200 legs

200 + 200 = 400 legs in total

50 deer + 100 peacocks = 150 heads in total
