1.	Quantity B: Ram has 30 storybooks, out of which he sells some at 2% profit and rest other at 6% profit. He gains 4% in the whole process. What is the profit amount collected from storybooks sold at 6% profit if Cost price of a storybooks is Rs. 120.1). Quantity A > Quantity B2). Quantity A < Quantity B3). Quantity A ≥ Quantity B4). Quantity A ≤ Quantity B
Answer» Quantity A: The cost price of products = Rs.300 GAIN % = 20% Selling price = Rs.360 Let marked price be Rs.a. Discount is 10% on marked price. 90% of a = 360 a = (360 × 100)/90 a = 3600/9 a = 400 The marked price of product is Rs.400 Quantity B: Ram has 30 storybooks. Some sold at 2% profit and some at 6%. In whole transaction he had 4% profit. The cost price of a storybook is Rs.120 Gain % = 4% Cost price of 30 storybooks = 30 × 120 = 3600 Gain % = [(SP – CP)/ CP] × 100 All Gain percentage are given, (Number of books sold at 2%)/(number of books sold at 6%) = (6 – 4)/(4 – 2) = 2/2 = 1/1 Number of books sold at 2% = number of books sold at 6% = 30/2 = 15 Cost price of 15 books = 15 × 120 = 1800 Selling price of 15 books at 6% = = [(100 + 6)/100] × 1800 = 1908 Profit amount of 15 books with 6% gain = = 1908 – 1800 = 108 From above solution, Relation between Quantity A > Quantity B is established.

Answer»

Quantity A:

The cost price of products = Rs.300

GAIN % = 20%

Selling price = Rs.360

Let marked price be Rs.a.

Discount is 10% on marked price.

90% of a = 360

a = (360 × 100)/90

a = 3600/9

a = 400

The marked price of product is Rs.400

Quantity B:

Ram has 30 storybooks.

Some sold at 2% profit and some at 6%.

In whole transaction he had 4% profit.

The cost price of a storybook is Rs.120

Gain % = 4%

Cost price of 30 storybooks = 30 × 120 = 3600

Gain % = [(SP – CP)/ CP] × 100

All Gain percentage are given,

(Number of books sold at 2%)/(number of books sold at 6%) = (6 – 4)/(4 – 2) = 2/2 = 1/1

Number of books sold at 2% = number of books sold at 6% = 30/2 = 15

Cost price of 15 books = 15 × 120 = 1800

Selling price of 15 books at 6% =

= [(100 + 6)/100] × 1800

= 1908

Profit amount of 15 books with 6% gain =

= 1908 – 1800

= 108

From above solution,

Relation between Quantity A > Quantity B is established.
