Question

The cost price of 16 books is equal to selling price of 30 books. Find gain%

Answer 1

Answer:

46.66% hope it helps

Step-by-step explanation:

CP=16

SP=30

Gain= SP-CP= 30-16=14

ratio of cp to gain = 14/30

7/15

Answer 2

Let the SP of 1 book = Rs 1

SP of 16 books = Rs 16

CP of 16 books = SP of 30 books

= Rs 30

SP of 30 books = CP of 16 books

= Rs 16

So, CP > SP

Loss = CP –SP

= 30 – 16

= Rs 14

$loss\% = \frac{loss}{c.p} \times 100 \\ loss\% = \frac{14}{30} \times 100 \\ loss\% = \frac{140}{3}\% \\ = 46 \frac{2}{3}$
