Question
(47.99/39.02) ÷ (11.99/12.99) X (143.99/47.87) ÷
(13.99/55.99) = ?² 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.)Solution
ATQ,
(47.99/39.02) ÷ (11.99/12.99) X (143.99/47.87) ÷ (13.99/55.99) = ?²
(48/39) ÷ (12/13) X (144/48) ÷ (14/56) = ?²
(48/39) X (13/12) X (144/48) X (56/14) = ?²
?² = 16
? = ±4
