Question

1) S.P is Rs.212, loss is Rs.12. Find C.P

2) CP is Rs.200, S.P is Rs.150. Find Profit or Loss

3) Discount is Rs.10, S.P is Rs.115. Find Marked Price​

Answer 1

P i) CP = Rs.. 1200, SP = Rs.. 1350
CP < SP. So, profit.
Profit = Rs. (1350 - 1200) = Rs. 150

(ii) CP = Rs. 980, SP = Rs. 940
CP > SP. So, loss.
Loss = Rs. (980 - 940) = Rs. 40

(iii) CP = Rs. 720, SP = ?, profit = Rs. 55.50
Profit = SP - CP
⇒ Rs. 55.50 = SP - Rs. 720
⇒ SP = Rs. (55.50 + 720) = Rs. 775.50

(iv) CP = ?, SP = Rs. 1254, loss = Rs. 32
⇒ Loss = CP - SP
⇒ Rs. 32 = CP - Rs. 1254
⇒ CP = Rs. (1254 + 32) = Rs. 1286
