Answers
Given : mallesh has some cow and some hens in his shed. total number of legs is 92 and the total number of heads is 29
To find : the number of cows in his shed.
Solution:
Let say number of Cows = C
Then number of hens = 29 - C ( as cow & hens have 1 head only )
Number of legs of cows = 4C
Number of legs of hen = 2(29 - C) = 58 - 2C
Total Legs = 4C + 58 - 2C = 58 + 2C
=> 58 + 2C = 92
=> 2C = 34
=> C = 17
number of cows in his shed. = 17
