Question

the cast of the cost of 12 pens is equal to the s ceiling price of 15 pens point find the loss percentage​

Answer 1

let the CP of 1 pen be Rs. 1

Then, CP of 12 pens = Rs.12

SP of 15 pens = Rs. 12

SP CP 1 pen = 12/15

Loss= CP - SP

=> 1-12/15

=> 15-12/15

=> 3/15

=> 1/5

Loss% = ( loss/CP × 100)%

=> (1/5 /1×100)%

=> (1/5×100)%

=> 20%

Loss% = 20%
