Question
(√899.69 + 49.83% of 640.24)² - (7/8 of 479.79) =
? What approximate value will come in place of question (?) in the following given expression? You are not expected to calculate the exact value.Solution
= (√899.69 + 49.83% of 640.24)² - (7/8 of 479.79 = (√900 + 50% of 640)² - (7/8 of 480) = (30 + 0.5 × 640)² - (7/8 × 480) = (30 + 320)² - 420 = 350² - 420 = 122500 - 420 = 122080 Answer: C
