Let the MP of a scooter = ₹ P
∴ CP of a scooter= ₹ 11P/13, Gain = 10%
SP = (110/100) x P= ₹ 11P/10
Gain = SP - CP = (11P/10 - 11P/13) = (143P - 110P)/130 = ₹ 33P/130Correct Option: C
Let the MP of a scooter = ₹ P
∴ CP of a scooter= ₹ 11P/13, Gain = 10%
SP = (110/100) x P= ₹ 11P/10
Gain = SP - CP = (11P/10 - 11P/13) = (143P - 110P)/130 = ₹ 33P/130
Gain percentage = (33P/130) x (13/11P) x 100 % = 30%

Let the CP be ₹ 100 and let MP be ₹ x above ₹ 100.
Then, MP = ₹ (100 + x) and discount =10%
∴ SP = [(90/100) x (100 + x)] = ₹ 177Correct Option: B
Let the CP be ₹ 100 and let MP be ₹ x above ₹ 100.
Then, MP = ₹ (100 + x) and discount =10%
∴ SP = [(90/100) x (100 + x)] = ₹ 177
⇒ x = 30
So, cost should be labelled at 30% above CP.

CP = ₹ 180, gain = 20%
∴ SP = (120/100) x 180 = ₹ 216
Let the MP be ₹ P.
Then, 80% of P = 216Correct Option: A
CP = ₹ 180, gain = 20%
∴ SP = (120/100) x 180 = ₹ 216
Let the MP be ₹ P.
Then, 80% of P = 216
∴ (80/100) x P = 216
⇒ P = (216 x 100)/80 = 270
Thus, MP is ₹ 270.

Let the fixed price of article = ₹P
Then, Selling price = 90% of P = (90 x P)/100 = ₹ 9P/10
Also, the selling price = 115% of 72 = ₹(115 x 72)/100
⇒ (115 x 72)/100 = 9P/10Correct Option: C
Let the fixed price of article = ₹P
Then, Selling price = 90% of P = (90 x P)/100 = ₹ 9P/10
Also, the selling price = 115% of 72 = ₹(115 x 72)/100
⇒ (115 x 72)/100 = 9P/10
∴ P = ₹ 92
- A showroom owner sells a leather jacket for ₹ P and claims to make a profit of 10%. He plans to have stall in the trade fair and marks the same jacket at ₹ 2P, at the stall, he allows a discount of 20%. What will be the percentage profit that he will make at the trade fair ?

SP at the stall at the trade fair = 2P - 20% of 2P = 8P/5
CP of the jacket = (P x 100)/(100 + 10) = 10P/11
∴ profit = 8P/5 - 10/11 = 38P/55Correct Option: C
SP at the stall at the trade fair = 2P - 20% of 2P = 8P/5
CP of the jacket = (P x 100)/(100 + 10) = 10P/11
∴ profit = 8P/5 - 10/11 = 38P/55
∴ Profit per cent made at the trade fair = [(38P/55) / (10P/11)]x 100
= (38/5) x (1/10) x 100
= 76%
