Question
What is the main constituent of
biogas?Solution
Methane (CH4) is the main constituent of biogas, typically making up about 50-75% of the gas produced during the anaerobic digestion of organic matter.
2.4 of 7.2 of 1/57.6 of 4200 = ?
245 + (45 ÷ 3 + 5) × 6 - 125 = ?
- 45% of 160 – 25% of 80 = 20% of ?
2*1/3 + 22*1/3 + 222*1/3 + 2222*1/2 + 22222*1/2 = ?
44.99% of 499.98 × (3.30/7.40)% of 1399.97 + 10.02 = ?
242 + 18 × 8 – ? = 356
- What will come in place of (?), in the given expression.
125% of 96 + 33% of 300 = ? (21 × 51 + 81)/(9 × 14 - 30) = ?
(2 ÷ 3) × (4 ÷ 12) × (? ÷ 10) × 45 × (1 ÷ 5) = (? ÷ 6) + (2 ÷ 5)
