Answer:
(1)a=8 and b=5;
(2)a=5 and b=7
Step-by-step explanation:
We know that,
Any number is divisible by 3 if the sum of its digit is divisible by 3 and any number is divisible by 5 if its last digit is 0 or 5.
Part (1):
This number is divisible by 5 if b is taken as 0 or 5. Since we need the larger number so .
Now we have the number
Now it is divisible by 3 if and only if
is divisible by 3.
is divisible by 3.
As we need the larger number, so we have .
Part (2):
This number is divisible by 5 if a is taken as 0 or 5. Since we need the larger number so
Now we have the number
Now it is divisible by 3 if and only if
is divisible by 3.
is divisible by 3.
As we need the larger number, so we have
