If a five digit number 247xy is divisible by 3, 7 and 11
Calculation:
LCM of 3, 7, 11 is 231
According to question
Largest possible value of 247xy is 24799
when we divided 24799 by 231 we get 82 as a remainder
Number = 24799 – 82
⇒ 24717
Now x = 1 and y = 7
(2y – 8x) = (2 × 7 – 8 × 1)
⇒ (14 – 8)
⇒ 6
∴ Required value is 6
