  2.    20 Cows
  3.    18 Cows
  4.    16 Cows
 Discuss Question
Answer: Option B. -> 20 Cows
Let initially X grass was present there,and it is increasing by Y grass per day, then for the first condition We get,X+24*y = 24*70 ----(1)For the 2nd condition, we have,X+60*Y = 60*30----(2)
Now, On solving equation (1) and (2), we get
X = 1600 and
Y = 10 /3
Third Condition,X+96*Y = 96 *N -----(3) [N = Number of Cows required]
Putting the values of X and Y in equation (3), We get
N = 20.
