(44.85% of 639.79 + 3/8 of 480.23) × (√63.84 –
19.99% of 499.71) = ? What approximate value will come in place of question (?) in the following given expression? You are not expected to calculate the exact value.Solution
(44.85% of 639.79 + 3/8 of 480.23) × (√63.84 – 19.99% of 499.71) = (45% of 640 + 3/8 of 480) × (√64 - 20% of 500 = (0.45 × 640 + (3/8) × 480) × (8 - 100) = (288 + 180) × (-92) = 468 × (-92) = -43056 Answer: E
