(a) Since 8, x, x, 50, are in proportion.
∴ x × x = 8 × 50
⇒ x2 = 400
∴ x = 20

(b) Since 36, 90, 90, x are in proportion.
∴ 36 × x = 90 × 90
⇒ x = \(\frac { 90\times 90 }{ 36 }\) = 225
∴ x = 225

Question 15.
The cost of 10 tables is ₹ 7500. Find the number of tables that can be purchased with ₹ 9000.
