# If the work done by (x-3) men in (2x+1) days :

If the work done by (x-3) men in (2x+1) days and the work done by (2x+1) men in (x+4) days are in the ratio 3:10, then what is the value of x?

- 3
- 6
- 9
- 12

**Answer: (2) 6 **

**Solution:-**

According to the question,

(X – 3) (2 X + 1) /(2 X + 1) (X + 4) = 3/10

(X – 3)/(X + 4) = 3/10

10 X – 30 = 3 X + 12

10 X – 3 X = 12 + 30

7 X = 42

X = 42/7

X = 6

Thus, the value of X is 6.

Hence, the correct answer is option (2) 6.
