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.) 245.01 ÷ 4.91 - √440 = √? - 50.92 ÷ 17.11Solution
ATQ,
245.01 ÷ 4.91 - √440 = √? - 50.92 ÷ 17.11
245 ÷ 5 - √441 ~ √? - 51 ÷ 17
49 - 21 ~ √? - 3
28 ~ √? - 3
√? ~ 31
? ~ 961
