Question
44.98% of 399.98 = ? x 19.98 - (39.98% of
2499.98) 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.)Solution
ATQ, 44.98% of 399.98 = ? × 19.98 – (39.98% of 2499.98) ? × 20 – (40% × 2500) ~ 45% × 400 ? × 20 – (40 × 25) ~ 45 × 4 ? × 20 – (1000) ~ 180 ? × 20 ~ 1000 + 180 ? ~ 1180/20 ? ~ 59
