Question
15.98% of 399.76 × 2.98 = ?% of
599.93 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, 15.98% of 399.76 × 2.98 = ?% of 599.93 16% of 400 × 3 ~ ?% of 600 64 × 3 ~ (?/100) × 600 ? ~ 192 × (100/600) ? ~ 32
