\frac{V}{A + B} = \frac{1}{4}.......(2)
To equate the ratio in the above equations, let us multiply (1) by 5 and (2) by 4.
So, A : B : V = 11 : 5 : 4
11 + 5 + 4 = 20 units
In 5 days, task completed = 20 × 5 = 100 units (total task)
Time taken by Bhuvan and Varun to complete the task
\frac{100}{4 + 5} = 11\frac{1}{9} \text{ days }
