# What will be the Value of n? If

A farmer divides his herd of n cows amongst his four sons, so that the first son gets one-half of the entire herd, the second son gets one-fourth while the third son gets one-fifth and the fourth son gets only 7 cows. The value of n is

- 240
- 100
- 180
- 140

**Answer: (4) 140
Explanation:-**

According to the question,

n – (n/2 + n/4 + n/5) = 7

n – 19n/20 = 7

n/20 = 7

n = 7 x 20

n = 140

Hence, the value of n is 140.
