What will come in the place of question mark (?) in the given expression?
(11/45) of 225 + 3 X 75 = ? X (72 ÷ 6 + 4)
(8.4 × 6.5 ×2.52 )/(5.04 ×3.25 ×2.1) = ?
- Simplify the following expression:
16 + [17 - (8 + 11) + 6 - 3] ÷ 0.2 (18 × 9 ÷ 6) × 3 = ?
1024 ÷ 16 + 800 ÷ √64 + ? = 200 * 2
315 ÷ 9 + 23 × 3+ 22 = ?× √441
65% of 102 + 14 = ? – 20
