Verified Answer
The price of 1 chair increased by 20% and that of 1 table decreased by...
Let the initial price of a chair and a table be Rs. ‘x’ and Rs. ‘y’ respectively
Hence, we have, 20x = 2y
⇒ x = y/10      ---- (1)
New price of a chair = (100 + 20)% of x = 1.2x
New price of 45 chairs = 45 × 1.2x = 54x
Substituting from (1),
New price of 45 chairs = 54 × (y/10) = 5.4y
New price of a table = (100 – 10)% of y = 0.9y
No. of tables costing equal to 45 chairs = 5.4y/0.9y = 6
∴ The new price of 45 chairs is equal to that of 6 tables
