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.) 17.5% of ? + √400.47 = 26.1% of 180.78Solution
ATQ,
17.5% of ? + √400.47 = 26.1% of 180.78
18% of ? + √400 ~ 26% of 181
(18/100) × ? + 20 ~ 47
(18/100) × ? ~ 47 – 20
? ~ 27 × (100/18)
? ~ 150
