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.
