Let the C.P. of article be Rs. 100.
∴ Marked price = Rs. 130S.P. = 130 × 90 = Rs. 117 100
∴ Profit% = 17%
ORRequired profit percent = x + y + xy % 100 = 30 − 10 − 30 × 10 % = 17% 100
Second Method :
Here, r = 30%
r_{1} = 10%Profit % = r × (100 − r_{1}) − r_{1} 100 = 30 × (100 − 10) − 10 100 = 30 × 90 − 10 = 17% 100 Correct Option: C

Marked price = Rs. 250
S.P. = Rs. 225
Discount = 250 – 225 = Rs. 25
If the rate of discount be x%, then250 × x = 25 100 ⇒ x = 25 × 100 = 10% 250
Second Method : Here, M.P. = Rs. 250, S.P. = Rs. 225Discount % = M.P. − S.P. = 100% M.P. = 250 − 225 × 100% = 10% 250 Correct Option: B
Marked price = Rs. 250
S.P. = Rs. 225
Discount = 250 – 225 = Rs. 25
If the rate of discount be x%, then250 × x = 25 100 ⇒ x = 25 × 100 = 10% 250
Second Method : Here, M.P. = Rs. 250, S.P. = Rs. 225Discount % = M.P. − S.P. = 100% M.P. = 250 − 225 × 100% = 10% 250
