Question : Directions: If θ denotes added to, δ denotes subtracted from, β denotes divided by, and α denotes multiplied by, then 5 β 1 δ 9 α 7 θ 142 = ?
Option 1: 114
Option 2: 98
Option 3: 84
Option 4: 125
Correct Answer: 84
Solution :
Given:
5 β 1 δ 9 α 7 θ 142 = ?
Replacing the symbols with mathematical signs, we get –
= 5 ÷ 1 – 9 × 7 + 142
= 5 – 9 × 7 + 142
= 5 – 63 + 142
= 147 – 63
= 84
The answer is 84. Hence, the third option is correct.
