Question
Saline soils are reclaimed
bySolution
The physical conditions of saline soil is good. The only problem with these soil is the presence of excess amount of soluble salts that limit crop production. So they are reclaimed by leaching and drainage
(2197)1/3 + (18)2 − 121 = ? − 69 × 5
Solve the following equation.
143 + 14.3 + 1.43 + 0.143 + 0.0143 =?
Simplify the following expression:
(√121 + √196) × 7 =? × 5
- What will come in the place of question mark (?) in the given expression?
62.5% of 120 + ? = (720 + 90) ÷ √36 (54/6) × 5 + 12 × (17/2) = ?% of 700
What is the value of 7/9-11/12+12/16-1/8?
- What will come in the place of question mark (?) in the given expression?
40% of (320 ÷ 4) + 2² X 25 = ? + 42 (13)2 - 3127 ÷ 59 = ? x 4
(2 ÷ 3) × (4 ÷ 12) × (? ÷ 10) × 45 × (1 ÷ 5) = (? ÷ 6) + (2 ÷ 5)
