Question

Which greatest digit should be there in the one’s place in 623___ to make it divisible by 2 but not 4​

Answer 1

Step-by-step explanation:

we can find the missing number by firstly finding the sum of digits of the given numbers and then subtract it from those multiple of 3, which are greater than this sum to get the smallest and greatest digits.

i) 6+7+2+4=19

multiples of 3 greater than 19 are 21,22,27,30

therefore, 21-19=2, 24-19=5, 27-19=8, 30-19=11

smallest digit=2 greatest digit=8

Answer 2

Answer:

greatest digit would be 8 and smallest one would be 2
