Correct Answer - Option 4 : 24
Calculation:
To check the divisibility by 88, it should be divisible by 11
Difference of sum of alternative terms should be 0
⇒ 5 + 4 + 3 = x + 2 + y
⇒ x + y = 10
To check the divisibility by 88, it should be divisible by 8
Last three digit should be divisible by 8
23y should be divisible by 8
For least value of y = 2, 23y is divisible by 8
For y = 2 and x = 8
the value of (5x – 8y) = (5 × 8 – 8 × 2)
⇒ 40 – 16 = 24
∴ The value of (5x – 8y) is 24
