Question

A chair costs Rs 250 and a table costs Rs 400 if a house wife purchased a certain no.of chairs and two tables for Rs2800 find the number of chairs she purchased

Answer 1

2800-2*400
2800-800=₹2000
2000/250
=8 chairs

Answer 2

Let x and y be the no.of chairs and tables
now,
250x + 400(2)=₹2800
250x=2800-800
250x=2000
x=2000/250
=200/25
=8

therefore she has brought 8 chairs
