Answer 1

Mritang can do the same piece of work in 38 days.

Step-by-step explanation:

Mritang is 50% more efficient than Fatima.

Mritang =work done by Fatima + 50% of work done by Fatima

Mritang = 1.5 of Fatima

Fatima can do a piece of work in 57 days.

Fatima can do work in one day = $\frac{1}{57}$

Work done by Mritang in one day = (1.5)1/57

                                                        = 1/38

                                                        = 38 days

Option a) 38 days.
