Question
20.05% of 450.05 – 15.15% of 119.99 × 4.02 =
? What approximate value should come in place of question mark (?) in the following question? (You are not expected to calculate the exact value)Solution
20.05% of 450.05 – 15.15% of 119.99 × 4.02 = ? => ? = 20% of 450 – 15% of 120 × 4 => ? = 90 – 18 × 4 => ? = 90 – 72 = 18
