Correct Answer - Option 3 : 5/3
GIVEN:
If the six-digit number 879xyz is exactly divisible by 7, 11 and 13
CONCEPT:
We know that, xyzxyz = xyz × 1001 = xyz × 7 × 11 × 13
CALCULATION:
Therefore, the six-digit number 879xyz exactly divisible by 7, 11, and 13.
⇒ The number will be 879879.
∴ x = 8, y = 7 and z = 9
According to question –
⇒ {(x + y) ÷ z} = {(8 + 7) ÷ 9}
⇒ 15/9
⇒ 5/3
