Question

A radio is sold for rs 3120 at a loss of 4 percent what will the gain or loss percent if it is sold for rs 3445

Answer 1

cp = sp×100/100-loss%

Answer 2

let the original price = x

now on selling it at rs 3120 at loss of 4%

so,

x-4/100*x = 3120

24x/25 = 3120

x = 3120*25/24

= 3250

so original price is 3250

now

profit would be there as 3445 > 3250

so

profit = profit/ original price * 100

3445- 3250/3250 * 100

= 195/3250 * 100

= 0.06*100

= 6

so there is gain of 6%
