Team Careers360 · Accepted Answer

Correct Answer: $\frac{80}{9}$ days

Solution : Time taken by Sachin to do the work = 10 days
Efficiency of Sachin = $\frac{1}{10}$
Efficiency of Anil = $\frac{112.5}{100}$ × efficiency of Sachin
= $\frac{112.5}{100}$ × $\frac{1}{10}$
= $\frac{112.5}{1000}$
= $\frac{9}{80}$
Time taken by Anil to do the work = $\frac{80}{9}$ days
Hence, the correct answer is $\frac{80}{9}$ days.
