Question
If 68 # 34 = 238 and 39 # 204 = 243, then 45 # 20 =
?Solution
The logic followed here is: 3 rd number: {(2 X 1 st number) + (3 X 2 nd number) }
68 # 34 = 238= {(2 X 68) + (3 X 34) } = {136 + 102} = 238
39 # 204 = 243= {(2 X 39) + (3 X 42) } = {78 + 126} = 204
45 # 20 = ? = {(2 X 45) + (3 X 20) } = {90 + 60} = 150.
(31.9)3 + (34.021)² - (16.11)3 - (42.98)² = ?

960.02 of 238.89 ÷ 144.01 of 79.97 = ?
- 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.)
320.98 + 49.99% of (261.09 + 138.98) = ?
? = 29.91% of 49.94% of ((56.25 × 4.09 + 23.01 × 7.89) × 99.98)
20.02% of (95.96 × 104.01 – 56.02 × 64.04) – ? = 12.02 × 39.96 + 103.03Â
