Question

⊕ and ⊙ are two operators on numbers p and q such that 

p ⊙ q = p - q, and p ⊕ q = p × q

Then, (9 ⊙ (6⊕ 7)) ⊙ (7 ⊕ (6 ⊙ 5)) = 

1. - 33
2. 40
3. - 40
4. - 26

Answer 1

Correct Answer - Option 3 : - 40

Explanation:

given,

p ⊙ q = p - q, and p ⊕ q = p × q, that means

⊙ = - (subtraction) and ⊕ = × (multiplication)

Then,

(9 ⊙ (6⊕ 7)) ⊙ (7 ⊕ (6 ⊙ 5)) = (9 - (6 × 7)) - (7 × (6 - 5)) = (9 - 42) - 7 = - 40

(9 ⊙ (6⊕ 7)) ⊙ (7 ⊕ (6 ⊙ 5)) = - 40
