Question
By which of the following can petrol fire be
extinguished ?Solution
The fires caused by the burning of inflammable materials like oil or petrol are also extinguished by using carbon dioxide fire extinguishers.
(117 + 93 - 10) ÷ 40 = ? - 12 X 2
√ (573 – 819 + 775) = ? ÷ 3
236.23-653.23+696.23=?
30% of 800 - ?2 = 15Â
2350 – 4830 + 9570 + 3350 – 1720 = ?
(12 × 48 ÷ 6) ÷ 2 + ? = 106
What will come in place of the question mark (?) in the following expression?
40% of 150 – ?% of 80 = 25% of 400
81% of 2300 – 34% of 550 = ?
 Simplify the given expression
[1.5 × 1.5 × 1.5 + 2.7 × 2.7 × 2.7 + 4.8 × 4.8 × 4.8 – 3 × 1.5 × 2.7 × 4.8] / [1.5 × 1.5 +2.7 × 2.7 ...
- What will come in the place of question mark (?) in the given expression?
40% of (320 ÷ 4) + 2² X 25 = ? + 42
