Rajan does $\frac{7}{11}$ of a work in 21 days. How many more days will he take to complete the work?
Answer & explanation
Correct answer: option 2
Rajan does \(\frac{7}{11}\) of a work in 21 days
Rajan does full work in = 21 × \(\frac{11}{7}\) = 33 days
To complete remaining work = 33 × \(\frac{4}{11}\)
= 12 days
