Answer 1

Answer:

10200 is the correct answer

Answer 2

Answer:

10200 is the answer.....

Explanation:

Given Numbers are 20,25,and 30.

Least common multiple (LCM) of given numbers is 300.

The smallest 5−digit number =10,000.

The number exactly divisible by LCM(20,25,30) is also divisible by 20,25,and 30.

When we divide the smallest 5−digit number by 300,100 is left as remainder .To make the number exactly divisible by 300,we add 200 in it and the number obtained is 10,200.

Hence,10,200 is the smallest 5−digit number exactly divisible by 20,25,and 30...
