Question
'N' is the largest three-digit number that leaves 4 as a
remainder when divided by 8, 14 and 10. Find the sum of digits of 'N'.Solution
LCM of (8, 14 and 10) = 280
Largest 3-digit number that is divisible by 280 = 280 × 3 = 840
So, N = 840 + 4 = 844
So, sum of digits of 'N' = 8 + 4 + 4 = 16
