Question

A chair costs Rs.250 and a table costs Rs.400.If a housewife purchased a certain number of chairs and two tables for Rs.2800,find the number of chairs she purchased.

Answer 1

Cost of tables purchased - 400 × 2 = Rs. 800
Money used to purchase chairs - Rs. 2800 - 800 = 2000
Cost of each chair - Rs. 250
Therefore, number of chairs bought - 2000 ÷ 250 = 8

Therefore the wife bought 8 chairs.

Answer 2

Answer:

8

Step-by-step explanation:

Given : A chair costs Rs.250 and a table costs Rs.400.

To Find : If a housewife purchased a certain number of chairs and two tables for Rs.2800,find the number of chairs she purchased.

Solution:

Let x be the number of chairs

Cost of 1 chair = Rs. 250

Cost of x chair = 250x

Cost of 1 table = Rs.400

So, cost of 2 tables = $400 \times 2 = 800$

We are given that a housewife purchased a certain number of chairs and two tables for Rs.2800

So, $250x+800=2800$

$250x=2800-800$

$250x=2000$

$x=\frac{2000}{250}$

$x=8$

Hence the number of chairs she purchased is 8.
