Question

15. 5 men do a piece of work in 12 days. In how
many days will 6 men complete the same
work?
(A) 8 days (B) 7 days
(C) 9 days (D) 10 days​

Answer 1

Answer:

As number of workers increase, time taken to complete the job decreases.

Therefore, it is an inverse proportion.

x1y1 = x2y2

5*12=6*X

=5*12/6=X

X=10.

therefore , option D is right
