Question
19.99% of 79.98 = ?2– 159.99% of
12.5 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, 19.99% of 79.98 = ?2 – 159.99% of 12.5 20% of 80 ~ ?2 – 160 of 12.5% ? 2 ~ (1/8) × 160 + 16 ?2 ~ 20 + 16 ? ~ √36 ? ~ 6
