Question

C.P = rupees 1250 , S.P. rupee 1000

Answer 1

cp= 1250

sp= 1000

loss= 1250-1000= 250

loss%= loss×100/cp

loss%=250×100/1250

loss%=20%

Answer 2

Loss = CP - SP = 1250 - 1000

= Therefore loss obtained is Rs 250

If required to find percentage of loss then

Formula to be implemented in loss%

Loss/Cost price x 100

250/1250 x 100 = 250/125 x 10

250/25 x 2 ( cancelled by 5 )

500/25 = 20%

Therefore loss% so obtained is 20%.
