Question
What approximate value will come in place of the question
mark (?) in the following question? (Note: You are not expected to calculate the exact value.) (580.65% of 85.12 – 1400.3 ÷ 6.93 + 305.65) × √256 = ? × 6.5Solution
ATQ,
((580.65% of 85.12 – 1400.3 ÷ 6.93 + 305.65) × √256 = ? × 6.5
(581 × 0.85 – 1400 ÷ 7 + 306) × √256 ~ ? × 6.5
(494 – 200 + 306) × 16 ~ ? × 6.5
? ~ 9526
