Solution

Let x be C.P. of the article

Let y % be both, the gain and loss made when the article is sold at ₹ 2,880 and ₹ 1,920 respectively. Then

`"x" + "y"/100 "x" = 2880`  ..........(i)

`"x" - "y"/100 "x" = 1920`  .............(ii)

Adding (i) and (ii), we get

2x = 4800

∴ x = 2400

i.e. C.P. of the article = ₹ 2400

Required profit percentage = 25%

∴ S.P. = C.P.`[1 + "Profit%"/100]`

= `2400[1 + 25/100]`

= `2400[1 + 1/4]`

= `2400 xx 5/4`

= 3000

∴ The article should be sold at ₹ 3000 to earn 25% profit.
