Given that , Selling Price of 12 kg of potatoes = Rs. 63
C.P. of 12 kg of potatoes = Rs. 63 × 100 = Rs. 60 105 ∴ C.P. of 50 kg of potatoes = 60 × 50 = Rs. 250 12
S.P. of 50 kg of potatoes = Rs. 247.50
Correct Option: A
Given that , Selling Price of 12 kg of potatoes = Rs. 63
C.P. of 12 kg of potatoes = Rs. 63 × 100 = Rs. 60 105 ∴ C.P. of 50 kg of potatoes = 60 × 50 = Rs. 250 12
S.P. of 50 kg of potatoes = Rs. 247.50
Loss = C.P. of 50 kg of potatoes - S.P. of 50 kg of potatoes
Loss = Rs. (250 – 247.50) = Rs. 2.5∴ Loss percent = 2.5 × 100 = 1% 250

Let the quantity of sugar at 8% profit be y kg.
∴ Quantity of sugar sold at 18% = (100 – y) kg
According to the question,y × 108 + (1000 - y) × 118 = 1000 × 114 100 100 100
Correct Option: D
Let the quantity of sugar at 8% profit be y kg.
∴ Quantity of sugar sold at 18% = (100 – y) kg
According to the question,y × 108 + (1000 - y) × 118 = 1000 × 114 100 100 100
⇒ 108y + 118000 – 118y = 114000
⇒ 118y - 108y = 118000 – 114000
⇒ 10y = 4000 ⇒ y = 400 kg

Here , S.P. of rice per kg = Rs. 54
∴ C.P. of rice per kg = 54 × 100 = Rs. 60 90
For 20% profit,S.P. per kg. = 60 × 120 = Rs. 72 100
Using the given formula :
Here , Loss% = 10%C.P. = S.P. 100 100 - Loss% C.P. = 54 100 100 - 10
C.P. = Rs. 60New S.P. = C.P. 100 + Profit% 100

Given in question , S.P. of article be Rs. 545.
Let C.P. of article be Rs. y.
According of the question,
625 – y = y – 545
⇒ 2y= 625 + 545 = 1170⇒ y = 1170 = Rs. 585 2
Correct Option: C
