Q:

A) 19 : 7 | B) 30 : 19 |

C) 8 : 15 | D) 31 : 17 |

Answer: C) 8 : 15

Explanation:

Explanation:

Given Lasya can do a work in 16 days.

Now, time taken by Srimukhi alone to complete the work = 16 x 100/80

Time taken by Rashmi = n days

=> (12 x 20)/(20 - 12) = (12 x 20)/n

=> n= 30 days.

Required ratio of efficiencies of Rashmi and Lasya = 1/30 :: 1/16 = **8 : 15.**
