Ramu can read a book perfectly well but cannot read the writing on black board unless he sits on the front row in class. Name the defect he has …………………..
Correct option is (A) 10/9
\(\because\) Krishna read in 1 hour = \(\frac{1}{3}\) part of a book
\(\therefore\) Krishna read in \(3\frac{1}{3}\) hours = \(3\frac{1}{3}\) \(\times\) \(\frac{1}{3}\) part of that book
= \(\frac{3\times3+1}{3}\) \(\times\) \(\frac{1}{3}\)
= \(\frac{10}{3}\) \(\times\) \(\frac{1}{3}\) = \(\frac{10}9\) part of the book.
