Question

If the number 713P8 is divisible by 3, then the smallest value of P is _________.​

Answer 1

the value of p is 6......

Answer 2

Answer:

Value of P=2

we know that,if a number is divisible by 3 only if sum of all it's digits make up a sum of a multiple of 3,or final value as 3,6 or 9

Ic 713P8 is divisible by 3,

then sum of all it's digit

that is

7+1+3+P+8= a multiple of 3

19+P=multiple of 3

We've to know,which is the closest number after 19,we can't go backwards,as you can't negative between it.

So,a multiple of 3,after 19 is 21

21-19=2

therefore the value of P must be 2

that is

7+1+3+2+8=21

21=2+1=3

hence, it's divisible by 3, therefore 2 is the answer
