Question

If the 8-digit number 136x5785 is divisible by 15,tjen find the least possible value of x

Answer 1

Answer:

it will be divisible by three if the sum of all 8 digits is divisible by three. 1+3+6+5+7+8+5 = 35. The lowest number which will add to make a multiple of three is the number 1. The least value of x which satisfies the requirement of being divisible by 15 is x=1.

Step-by-step explanation:it will be divisible by three if the sum of all 8 digits is divisible by three.

Answer 2

Answer: 1

Step-by-step explanation: To be divisible by 15 a number has to be divisible by 3 and 5.

To be divisible by 5 the number must end in 0 or 5.

As the number is ending with 5 so it is divisible by 5.

For divisible by 3 the sum of the digits will be divisible by 3.

Sum of all the digits=1+3+6+x+5+7+8+5=35+x

so x=1,4 and 7

Minimum is 1
