Answer 2

$\huge\underline\mathfrak\pink{Question}$

Sita bought 10 notebooks for rs 50 and sold them at rs 5 . 50 per note book . find her gain percent.

$\large{\sf{\pink{Answer-}}}$

CP of 10 books = 50

CP of one book = $\frac{50}{10}$ = Rs.5

SP of one book = 5.50

gain = 4.50 - 5 = 0.74

gain percent = $\frac{0.74}{5}$  × 100

                     = 15 × 20

                      = 300%
