Question

B) Rahul sold a laptop for 20,000 (a) If he incurred a loss of 20%, find the cost price of the laptop. (b) Find the amount for which he should have sold the laptop to gain a profit of 10%​

Answer 1

$1. \\ \: 20000 \times \frac{20}{100} \\ = 200 \times 20 = 4000 \\ 2. \\ 20000 \times \frac{10}{100} \\ = 200 \times 10 = 2000$

Answer 2

Answer:

(a) 25,000 (b) 27,500

Step-by-step explanation:

(a) Let the CP = x

then, x * 80% = 20,000

x = 20,000 * 100/80

x = 25,000 = CP

(b) Now here the CP will be 25,000.

So, SP = 25,000 + 25,000*10%

= 25,000 + 2,500 = 27,500
