1. Select the correct answer in each of the following

1. If 5×6 is exactly divisible by 3, then the least value of x is

a) 0
b) 1
c) 2
d) 3

Solution: we know that the sum of the digits of a number is divisible by 3 then the whole number is divisible by 3

5+x+6 = multiple of 3

11+x= 0, 3, 6, 9….

11+x= 12

∴ x=12-11 = 1

The least value of x is 1

2. If 64y8 is exactly divisible by 3, then the least value of y is

a) 0
b) 1
c) 2
d) 3

Solution: we know that the sum of the digits of a number is divisible by 3 then the whole number is divisible by 3

6+4+y+8 = multiple of 3

18+y= 0, 3, 6, 9….

18+y= 18

∴ y=18-18 = 0

The least value of y is 0

3. If 7×8 is exactly divisible by 9, then the least value of x is

a) 0
b) 2
c) 3
d) 5

Solution: we know that the sum of the digits of a number is divisible by 9 then the whole number is divisible by 9

7+x+8 = multiple of 9

15+x= 0, 9, 18, 27….

15+x= 18

∴ x=18-15 = 3

The least value of x is 3

4. If 37y4 is exactly divisible by 9, then the least value of y is

a) 2
b) 3
c) 1
d) 4

Solution: We know that the sum of the digits of a number is divisible by 9 then the whole number is divisible by 9

3+7+y+4 = multiple of 9

14+y= 0, 9, 18, 27….

14+y= 18

∴ y=18-14 = 4

The least value of y is 4
