Answer 1

Answer:

A=1 ,B= 5

2351115

Step-by-step explanation:

A number is divisible by 5 when it ends in either 0 or 5.Since 'A' has to be less than 'B' we choose 5 for B.

The number will be divisible by 3 when the sum of its numbers are divisible by 3. Excluding A, the sum becomes 17. 18 is the nearest digit divisible by 3, So we can choose 1 for A.
