Answer 1

Question -

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

Answer -

• COST OF A CHAIR = 250
• COST OF A TABLE = 400

Let Number of Chair = x

And Number of Table = 2

The Cost = 2800

• $\rm\dashrightarrow{}$ x × 250 + 2 × 400 = 2800
• $\rm\dashrightarrow{}$ 250x + 800 = 2800
• $\rm\dashrightarrow{}$ 250x = 2800 - 800 = 2000
• $\rm\dashrightarrow{}$ X = 8

Number of Chair = 8
