If ⊕ is an operation such that
a ⊕ b = 2a when a > b
= a + b when a < b
= a² when a = b,then, 
(5 ⊕ 7) + (4 ⊕ 4) 
is equal to : 3(5 ⊕ 5) - (15 ⊕ 11) - 3

Correct Option: C
a ⊕ b = 2a if a > b
= a + b if a < b
= a² if a = b,
| ∴ | |
| 3(5 ⊕ 5) - (15 ⊕ 11) - 3 |
| = | |
| 3 × 5² - 2 × 15 - 3 |
| = | = | = | |||
| 75 - 30 - 3 | 42 | 3 |
