Question
Which seed treatment method involves dry seeds being
placed in containers and covered with concentrated Sulphuric acid (H2SO4) or HCl in the ratio of one part of seed to two parts of acid?ÂSolution
• Acid scarification: Dry seeds are placed in containers and covered with concentrated Sulphuric acid (H2SO4) or HCl in the ratio of one part of seed to two parts of acid. • The amount of seed treated at any time should be restricted to not more than 10kg to avoid uncontrollable heating.
180 % of 45 + √144 × 8 = ?2  + 80 % of 70
(5/8 + 7/12) x 168 = ? + 93 - 25
√? × 4 - 374 + 127 + 300 = 117
360 ÷ 9 + 15 % of 200 + ? * 10 = 45 * √25
If A = 0.84181818... then what will be the difference between the numerator and denominator of the lowest fraction form of A?
What will come in the place of question mark (?) in the given expression?
9 (? + 12) = 3 (14 + 17 - 11)
(360 - ?)/(25% of 96) = 13
(16% of 550 – 22% of 700 + 45% of 800) = ?
52% of 400 + √(?) = 60% of 600 - 25% of 400
140% of 1270 + 60% of 2085 = 1881 + ‘?’% of 287
