Question

Six men can do a certain piece of work in 5x+ 6 days and 11 men can do the work in 3x days.then the value of x is?

Answer 1

Answer:

6men.........5x+6

=>1men.......5x/6+1. Equation1

11 men......3x

=>1men.......3x/11. Equation2

From equation1 and equation2

5x/6+1=3x/11

Here x <-1.5 but this is not possible since from equation 1 and 2 days become negative. Mathematically correct but conceptually wrong
