Question

Find the least 5 digit Number which is exactly divisible to 20 , 25 and 30 .

Answer 1

LCM of 20, 25, 30 =300

Least 5 digit number is 10000.

and 10000/300=33.3, whose integer part is 33.

If we calculate 33 * 300= 9900, which is not a 5 digit number. So ignore it.

The number which comes after 33 is 34.

and 34*300=10200, is the answer
