2. =, ÷, ×

3. =, ×, ÷

4. ÷, =, ×

Appropriately replaces \(\circledast \) ⊕ and ⊙  respectively in 90 \(\circledast\)  6  ⊕ 8 ⊙ 2 ?

1. 1
2. 2
3. 3
4. 4

Answer 1

Correct Answer - Option 4 : 4

Given: 90 \(\circledast\)  6  ⊕ 8 ⊙ 2 

Analyzing the options:

1. ×, =, ÷ → 90 \(\circledast\)  6  ⊕ 8 ⊙ 2 → 90 × 6 = 8 ÷ 2 → 540 = 4 → False

2. =, ÷, × → 90 \(\circledast\)  6  ⊕ 8 ⊙ 2 → 90 = 6 ÷ 8 × 2 → 90 = 1.5 → False

3. =, ×, ÷ → 90 \(\circledast\)  6  ⊕ 8 ⊙ 2 → 90 = 6 × 8 ÷ 2 → 90 = 24 → False

4. ÷, =, × → 90 \(\circledast\)  6  ⊕ 8 ⊙ 2 → 90 ÷ 6 = 8 × 2 → 15 = 16 → True (In this case, the difference between LHS and RHS is smallest. Therefore, out of the given options, this option is the best possible case.)

Hence, option 4 is the correct answer.
