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.) √575 X 6.12 + √257 - ? = 14.83% of 379.87 + 147.11 ÷ 6.98Solution
ATQ, √ 575 X 6.12 + √ 257 - ? = 14.83% of 379.87 + 147.11 ÷ 6.98 √ 576 X 6 + √ 256 - ? = 15% of 380 + 147 ÷ 7 24 X 6 + 16 - ? ~ 57 + 21 144 + 16 - ? ~ 78 ? ~ 160 - 78 ? ~ 82
