Question
CO₂ enrichment is most effective
when:Solution
Closing the greenhouse prevents CO₂ from escaping, and light is necessary for photosynthesis to occur. This can increase yields by up to 30% for many vegetable crops.
[192 ÷ 6 × 5] ÷ (? + 3) = 20
What will come in the place of question mark (?) in the given expression?
(125 × 64) ÷ (8 × 5) + (12.5)² – (144 ÷ 3) = ?
...What will come in the place of question mark (?) in the given expression?
(40% of ? × 43 ) – 232 = 751
The income of a person is Rs.15000 and his expenditure is Rs.12000. In the next year his income and expenditure is increased by 8% and 13% respectively....
15% of 695 – 12.5% of 250 =? – 1200
Simplify the following expressions and choose the correct option.
{[(96 ÷ 3) × (5/8)] + 7²} ÷ 9 = ?
26 2 – 13% of 400 + (529 ÷ 23 2 ) = ? 2
Evaluate: 84 ÷ 7 × (3 + 5) − 2³
31% of 1900 - ? = 73
535 + ? × 27 - 22 × 20 = 230
