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.) √? X 8.07 = (959.91 - 120.11) ÷ (48.11 - 42.96)Solution
ATQ, √? X 8.07 = (959.91 - 120.11) ÷ (48.11 - 42.96) √? X 8 ~ (960 - 120) ÷ (48 - 43) √? X 8 ~ 840 ÷ 5 √? X 8 ~ 168 √? ~ 21 ? ~ 441
