What will be the approximate value of the following
questions. (74.75% of 600.29 – 44.85% of 399.99) × (√224.95 ÷ 15.01) = ?Solution
(74.75% of 600.29 – 44.85% of 399.99) × (√224.95 ÷ 15.01) = (75% of 600 - 45% of 400) × (√225 ÷ 15) = [(0.75 × 600) - (0.45 × 400)] × (15 ÷ 15) = [450 - 180] × 1 = 270 Answer: A
