76 ladies complete a job in 33 days. Due to some reason some ladies did not join the work and therefore it was completed in 44 days. The number of ladies who did not report for the work is

  1. 17
  2. 18
  3. 19
  4. 20

Answer

W = M1 x D2 = M2 x D2

76 x 33 = M2 x 44

M2 = 57

Number of ladies did not report = 76 - 57 = 19

The correct option is C.
