Question

1. Manas purchased a refrigerator for ₹18000 and a microwave ₹10500.If he lost

5% on the sale of the refrigerator but gained 17% on the sale of the microwave,

What was his total gain or loss percent​

Answer 1

Step-by-step explanation:

ref cp =18000

lost%=5%

$sp = ( \frac{100 - 5}{100} ) \times cp \\ = 0.95 \times 18000 \\ = 17100$

micro cp= 10500

profit % =17%

$sp = ( \frac{100 + 17}{100} ) \times cp \\ = 1.17 \times 10500 = 12285$

total cp= 28500

total sp = 29385

profit= 885

p%= (885/28500)*100

=3.105%
