Question

anshu sold two calculators at rs 198 each. on one she gained 10%. what is the cp of each calculator? find total gain or loss percent

Answer 1

Answer:

10%

Step-by-step explanation:

selling of each calculator = 198

profit on each = 10%

cost price =

$\frac{100 }{100 + profit} \times selling \: price$

cost price of one calculator is

$\frac{100}{100 + 10} \times 198 \\ \\ \frac{100 \times 198}{110} \\ \\ 180$

cost price of both calculator = 180+180= 360

total selling price = 198+198 = 396

total profit = SP - CP

396-360

36

profit%

$\frac{profit}{cp} \times 100 \\ \\ \frac{36}{360} \times 100 \\ \\ 10\%$
