Answer:
Step-by-step explanation:
Let the number of chairs be x .
Cost of 1 chair = Rs 250.
Cost of 1 Table = Rs. 400.
Given housewife purchased a certain number of chairs and two tables for 2800.
=> 250*x + 2 * 400 = 2800
=> 250x = 2800 - 800
=> 250x = 2000
=> x = 2000/250 = 8.
Thus the housewife bought 8 chairs.
