Let N is the least number of six digits which when divided by 4, 6, 10, 15 leaves 3 as a remainder. The sum of all digits of N is.
Answer & explanation
Correct answer: option 4
LCM of 4, 6, 10, 15 = 60
Least number of six digits = 1,00,000
When 1,00,000 is divided by 60 the remainder = 20
So least number of six digit, which is completely divisible by 60 = 1,00,020
Therefore, N = 100020 + 3 = 100023
Sum of digits = 1 + 2 + 3 = 6
