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.) 75.98% of 700.01 - 90.11% of 399.98 = ? ÷ (45.01 X 2.92 - 129.11)Solution
ATQ,
75.98% of 700.01 - 90.11% of 399.98 = ? ÷ (45.01 X 2.92 - 129.11)
76% of 700 - 90% of 400 ~ ? ÷ (45 X 3 - 129)
532 - 360 ~ ? ÷ (135 - 129)
172 ~ ? ÷ 6
? ~ 1032
