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.) (10.98³- 31.12²) ÷ (8.92²- 76.11) = ? X 4.11 - (13.11²- 2.91)Solution
ATQ,
(10.98³- 31.12²) ÷ (8.92²- 76.11) = ? X 4.11 - (13.11²- 2.91)
(11³- 31²) ÷ (9²- 76) ~ ? X 4 - (13²- 3)
(1331 - 961) ÷ (81 - 76) ~ ? X 4 - (169 - 3)
370 ÷ 5 ~ ? X 4 - 166
74 ~ ? X 4 - 166
? X 4 ~ 240
? ~ 60
