Correct Answer

Explanation

According to the calculation,
the ratio of the time it takes Sakshi to complete the work to the time it takes Tanya to complete the work is 5:4.
This means that for every 5 units of time it takes Sakshi to complete the work,
it takes Tanya 4 units of time.
Using this information,
we can determine that Tanya will take 16 days to complete the work.
This is calculated by setting up a proportion using the ratio of the time it takes Sakshi to complete the work to the time it takes Tanya to complete the work and the known value of 20 days for Sakshi.
The proportion is 5:4 :: 20:x,
and solving for x gives us a value of 16 days
