Question

S, M, E and F are working in shifts in a team to finish a project. M works with twice the efficiency of others but for half as many days as E worked. S and M have 6 hour shifts in a day, whereas E and F have 12 hours shifts. What is the ratio of contribution of M to contribution of E in the project?

• A.
  1 : 1
• B.
  1 : 2
• C.
  1 : 4
• D.
  2 : 1

Answer 1

The correct option is B

1 : 2
(b)
M works with twice efficiency as E but worked for half as many days.

So in this repsect they will do equal work if their shifts would have been for same timings.

But M's shift is for 6 hrs, while E's shift for 12 hrs.

Hence E will do twice the work as M.

Ratio of contribution of M : E in work, 1 : 2
