Question : Directions: In the following question, using which mathematical operators will the expression become correct? 69 ? 3 ? 2 ? 9 ? 3
Option 1: ÷, –, >, and ×
Option 2: ÷, +, <, and ×
Option 3: ÷, –, =, and ×
Option 4: ×, +, <, and ×
Correct Answer: ÷, +, <, and ×
Solution : Given: 69 ? 3 ? 2 ? 9 ? 3
Replace ? with the mathematical signs and solve the equations one by one using BODMAS. First option: ÷, –, >, and × 69 ÷ 3 – 2 > 9 × 3 23 – 2 > 27 21 ≯ 27 Second option: ÷, +, <, and × 69 ÷ 3 + 2 < 9 × 3 23 + 2 < 9 × 3 25 < 27 Third option: ÷, –, =, and × 69 ÷ 3 – 2 = 9 × 3 23 – 2 = 9 × 3 21 ≠ 27 Fourth option: ×, +, <, and × 69 × 3 + 2 < 9 × 3 207 + 2 < 27 209 ≮ 27
So, only the second option satisfies the given equation. Hence, the second option is correct.
