(11/12) × (18/22) × (4/3) + 3 = ?2
- What will come in the place of question mark (?) in the given expression?
32% of 74% of ? = 16% of 37% of 180 30% of 215 + 135% of ? = 469.5
800 + 900 X (3)-2 - ? = 25 X 60 ÷ 2
1555.5 + 1000.8 – 1354.3 = ? + 52
- What will come in place of (?), in the given expression.
(4² + 6²) × 2 = ? - 55% of 220 – 15% of 40 = 20% of ?
50 ÷ 2.5 × 64 + ? = 1520
(-251 × 21 × -12) ÷ ? = 158.13
