Question

Q22. Ramesh is twice as good a workman as Sunil and finished a piece of work in 3 hours less than Sunil. In how many hours, 1 together could finish that piece of work?

• A. a) $2\frac{1}{3}$
• B. b) 2
• C. c) $1\frac{2}{3}$
• D. (d) None of the above

Answer 1

The correct option is B

b) 2

Ramesh works as much as two Sunils would do

Suppose Ramesh takes x hours then Sunil would take 2x hours.

Therefore, x= 3

Time taken if Ramesh and Sunil work together = $\frac{3x6}{3+6}=2$
