Answer:

7

Step-by-step explanation:

the answer is 7 because

Answer 2

Divisibility test of 3

sum of the digits should be divisible by 3

So,

....6724

smallest digit needed to be added

6+7+2+4 = 19

the multiple of 3 just above 19 = 21

21 - 19 = 2

So the number that should be added is 2

greatest number to be added

6+7+2+4 = 19

19 + 8 =27

So the greatest number to be added = 8

Similarly,

4765...2

4+7+6+5+2 =24(divisible by 3)

smallest number to be added = 0

greatest number to be added = 6

Divisibility test of 6

sum of numbers should be divisible by 3 and 2

297...44

sum = 26

next multiple= 30

Number that can be added = 4 only( consider the next multiples,the number to be added will be 2 digits)

438.....50

sum = 20

next multiple= 24

numbers that can be added = 4
