**Q1. Rishabh can do a work in 24 days. The ratio of working efficiency of Shashank and Keshav is 4 : 5 and efficiency ratio of Rishabh and Shashank is 3 : 4. In how much time Keshav will complete the same work ?**

18.4 days

16 days

14.4 days

16.4 days

12 days

Solution:

C

S : K = 4 : 5 and R : S = 3 : 4

S = working efficiency of Shashank

K = working efficiency of Keshav

R = working efficiency of Rishabh

∴ S : K : R = 4 : 5 : 3

Time ratio of Shashank, Keshav and Rishabh respectively

= 1/4 :1/5 :1/3 = 15 : 12 : 20

∴ Required answer = (12/20) ×24 = 14.4 days

S : K = 4 : 5 and R : S = 3 : 4

S = working efficiency of Shashank

K = working efficiency of Keshav

R = working efficiency of Rishabh

∴ S : K : R = 4 : 5 : 3

Time ratio of Shashank, Keshav and Rishabh respectively

= 1/4 :1/5 :1/3 = 15 : 12 : 20

∴ Required answer = (12/20) ×24 = 14.4 days
