Question
Which of the following is not the objective of puddling
in riceSolution
Puddling is done in rice to reduce weed infestation, increase water retention in soil by reducing percolation losses and to increase availability of iron and phosphorous.
- Evaluate: 156 ÷ 12 × 4 + 180 – 40% of 350
What will come in the place of question mark (?) in the given expression?
642 - 362 = ? X √1225
- What will come in place of (?), in the given expression.
60% of 150 + 0.25 × 200 = ? If (7a + b) : (7a - b) = 7:3, then find the value of a:b?
√729 × 5 + 270 - 3 ÷ ∛27 + 4 × ? = 484
8 × 12 + 110 ÷ 5 = 72 + ?
16/15 of 21/28 of 321.5 = ?
[(82 × 162)/12] - 28 = ?
15% of 2400 + (√ 484 – √ 256) = ?
Find the value of (x + y)² - (x - y)², where x = 15 and y = 7.
