Answer 2

Tanya needs 18 days to complete 75% of work.

Step-by-step explanation:

Since we have given that

Number of days Arjun can do to finish a work alone = 12 days

Work done by Arjun = $\dfrac{1}{12}$

Number of days Arjun and Tanya can do to finish a work together = 8 days

Work done by both = $\dfrac{1}{8}$

According to question, the number of days Tanya needs to complete its work is given by

$\dfrac{1}{8}-\dfrac{1}{12}\\\\=\dfrac{3-2}{24}\\\\=\dfrac{1}{24}$

So, Number of days to complete 75% of work is given by

$24\times \dfrac{75}{100}=24\times \dfrac{3}{4}=6\times 3=18$

Hence, Tanya needs 18 days to complete 75% of work.
