25% of 60 × 15% of 120 = 30% of (?)
262 × 15 + (?)² = 4099
20% of 550 × 25% of 80 = ?2 × 22
(15 × 225) ÷ (45 × 5) + 480 = ? + 25% of 1240
Ravi is 12 years younger than Surya. Ravi's age is 40% of the sum of his and Surya's age. What will be Surya's age 9 years hence?
115 ÷ 23 + 12 × 6 = ? + 16 - 35
3.55 + 1.05 + 2.5 × 13 – 12% of 12.5 = ?
120% of 400 + ?% of 520 = 1000
432 ÷ ? × 2552 ÷ 44 = 2088
