Question
[(2/3 of 599.77) + (39.69% of 450.14)] ÷ [(5/8 of
399.79) - √120.91] = ? What approximate value will come in place of question (?) in the following given expression? You are not expected to calculate the exact value.Solution
[(2/3 of 599.77) + (39.69% of 450.14)] ÷ [(5/8 of 399.79) - √120.91 = [(2/3 of 600) + (40% of 450)] ÷ [(5/8 of 400) - √121] = [(2/3 × 600) + (0.4 × 450)] ÷ [(5/8 × 400) - 11] = [400 + 180] ÷ [250 - 11] = 580 ÷ 239 = 2.42 = 2 Answer: A
