Question

of a commodity is sold at 15% profit, ¼ is sold at 20% profit and the rest at 24% profit. If the Total profit is Rs. 80 is earned then find the value of commodity?
A) 350
B) 410
C) 400
D) 300

Answer 1

rmula: Loss = Cost price (C.P.) – Selling Price (S.P.)

Profit or Loss is always calculated on the cost price.

Marked price: This is the price marked as the selling price on an article, also known as the listed price.

Discount or Rebate: This is the reduction in price offered on the marked or listed price.

Below is the list of some basic formulas used in solving questions on profit and loss:

Gain % = (Gain / CP) * 100

Loss % = (Loss / CP) * 100

SP = [(100 + Gain%) / 100] * CP

SP = [(100 – Loss %) / 100]*CP

The above two formulas can be stated as,
If an article is sold at a gain of 10%, then SP = 110% of CP.
If an article is sold at a loss of 10%, then SP = 90% of CP.

CP = [100 / (100 + Gain%)] * SP

CP = [100 / (100 – Loss%)] * SP

Answer 2

Answer:

C) 400

Step-by-step explanation:

Correction in question:- 1/3rd of a commodity is sold at 15% profit, ¼ is sold at 20% profit and the rest at 24% profit. If the Total profit is Rs. 80 is earned then find the value of commodity?

Answer :- Commodity sold at 24% profit = 1 - (1/3 + 1/4) = 1 - 7/12 = 5/12

Value of commodity = x

Profit = 80

80 = x (1/3 x 15) + x (1/4 x 20) + x (5/12 x 24)

∴ x = 400
