Question

a three digit number 4bc is divisible by 15. what are the values of band c for the smallest such number.​

Answer 1

Answer:

b=0 and c=5

Step-by-step explanation:

4bc is divisible by 15

15=3*5.thus it is divisible by 3 and  5 both

i) divisibility by 3

sum of digits of 4bc

=4+b+c is divisible by 3

ii) Divisibility by 5

unit digit c =0 or 5

If c=0

then 4+b+c=4+b disivisible by 3

for smallest number b=5

So No=450

If c=5

then 4+b+c=4+b+5=9+b

b can be zero,Then No =405

So possible number are 450 or 405

The smallest No=405

so b=0 and c=5

Answer 2

Answer:

b = 0 , c = 5
