Deficiency of NITROGEN yellowing of leaf in a plant appears on __ ?
N is highly mobile in plants so its deficiency occurs in lower or older leaves
The value of 3 × 7 + 5 – 6 ÷ 3 – 9 + 45 ÷ 5 × 4 – 45 is:
(1225/25) - (192/96) + (50/5) = ?
9/5 × 18/25 ÷ 42/21 = ? - 82/75
44% of 1250 + 46 × 34 = 40% of ? + 1154
30% of 2200 +’?’ x 50 – 1020 = 11x 306 + (√ 2250 ÷ 0.1)
25% of 300 + √(?) = 35% of 600 - 15% of 300
7(1/5) – 3(1/4) + 8(3/4) = ?
10% of 80% of 50% of ? = 4
