Determine the simplified value of the given mathematical expression.
{(80% of 650 + 25 × 12) – 20 × ?} = 760
(342 – 20% of 5280) = ? ÷ 3
- What will come in place of (?) in the given expression.
(25% of 320) + (15% of 240) = ? √4761 ÷ 23 + √12769 = ? × 58
- What will come in the place of question mark (?) in the given expression?
5/13 × 104 + 1(2/9) × 198 = 133 + ?
40% are the passing marks. A student gets 250 marks yet fails by 38 marks. What is the maximum marks?
1360 ÷ 8 + 490 ÷ √49 + ? = 150 × 2
