Step-by-step explanation:

$\blue{\bold{\underline{Question}}}$

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

$\blue{\bold{\underline{Answer}}}$

$\blue{\bold{\underline{Given}}}$

Cost of chair=250

Cost of table =400

Let the number of chairs bought be n

Now,

n*250+2*400=2800

250n+800=2800

250n=2800-800=2000

250n=2000

n=2000/250=8

Therefore,Number of chairs bought is 8

Solution

★ Let the number of chair be x

According to the given condition

A housewife purchased a certain number of chairs and two tables for Rs. 2800.

➟ 250x + 400 × 2 = 2800

➟ 250x + 800 = 2800

➟ 250x = 2800 - 800

➟ 250x = 2000

➟ x = 2000/250

➟ x = 8

Hence,

• Number of chairs purchased = 8
