What will come in the place of question mark (?) in the given expression?
(72 × 6 ÷ 12) × 6 = ?
(16% of 550 – 22% of 700 + 45% of 800) = ?
4387897 – 3286871 – 51926 = ?
√1936 + √3025 = ? % of 220
104 × 21 ÷ 13 + ? % of 300 = 320 + 22
555.05 + 55.50 + 5.55 + 5 +0.55 = ?
3.55 + 1.05 + 2.5 × 13 – 12% of 12.5 = ?
18 * 9 + 25% of 120 + 50% of 200 = ?
62 of 8 - 320 ÷ 4 = ?3 + 200
