Question 1:

Find the SP when:

(i) CP = Rs 950, gain = 6%

(ii) CP = Rs 9600, gain = 1623%

(iii) CP = Rs 1540, loss = 4%

(iv) CP = Rs 8640, loss = 1212%

ANSWER:

(i) CP = Rs. 950

Gain = 6%

SP ={(100 + Gain%)100× CP } = {(100 + 6)100× 950} = 106100× 950 = 100700100 = Rs. 1007

(ii) CP = Rs. 9600

Gain = 1623% = 50 3%

SP={ (100 + Gain%)100× CP} = {(100 + 503)100× 9600} = 350300 ×9600 = 33603 = Rs. 11200

(iii) CP = Rs. 1540

Loss = 4%

SP={(100 − Loss%)100× CP} = {(100 − 4)100× 1540} = 96100× 1540 = 147840100 = Rs. 1478.40

(iv) CP = Rs. 8640

Loss = 1212% = 252%

SP={(100 − Loss%)100× CP} = {(100 − 252)100× 8640} = 175200× 8640 = 1512000200 = Rs. 7560
