1) C.P. = ₹50, S.P. =₹ 60
3) C.P. = ₹12,000, S.P. = ₹9000
2) C.P.= ₹1250, S.P. = ₹1000
4) C.P. = ₹20.00, S.P. = ₹19.50​

Answer 1

Answer:

1) Gain% = 20 % , 3) Loss% = 25% , 2) Loss% = 20% , 4) Loss% =2.5%

Step-by-step explanation:

1) C.P. = Rs50 , S.P. = Rs60

Gain = (SP) - (CP)

= Rs60 - Rs50

= Rs 10

Gain% = (Gain/CP × 100)%

= (10/50 × 100)

= 20 %

3) C.P. = Rs12000 , S.P. = Rs9000

Loss = ( C.P. ) - (S.P.)

= Rs12000 - Rs9000

= Rs 3000

Loss% = (Loss/CP × 100)%

= (3000/12000 × 100)%

= 25%

2) C.P. = Rs 1250 , S.P. = Rs 1000

Loss = ( C.P. ) - (S.P.)

= Rs 1250 - Rs 1000

= Rs 250

Loss% = (Loss/CP × 100)%

= (250 /1250 × 100)%

= 20%

4) C.P. = Rs 20.00 , S.P. = Rs 19.50

Loss = ( C.P. ) - (S.P.)

= Rs 20.00 - Rs 19.50

= Rs 00.50

Loss% = (Loss/CP × 100)%

= (00.50/20.00 × 100)%

= (50/2000 × 100)%

=2.5%
