Answer 1

Answer:

a:b = 3:2

Explanation:

                                              Candle                         Pen

Cost Price                                  x                                2x

Selling Price                              a                                 b

Profit percent (profit %) = $\frac{3b}{10} *100$ -------------------first condition

Loss % = $\frac{4a}{20x} *100$ -------------------SECOND condition

PROFIT % = LOSS %

$\frac{3b}{10} *100 = \frac{4a}{20x} *100$

a:b = 3:2
