A) 26
B) 24
C) 23
D) 22
Correct Answer: A
Solution :
Let no. of hen =x and no. of cows = y Now, total no. of heads = 48 \[\frac{SP}{M-SP}=\frac{100-d}{100}\]\[\because \] ...(1) And total no. of feet = 140 Now, hen has 2 feet and cow has 4 feet \[\frac{SP}{15}=\frac{100-20}{20}\] \[SP=\frac{80}{20}\times 15=Rs.60\] ...(2) On solving equation (1) and (2), we get y = 22 and x = no. of hen = 26.You need to login to perform this action.
