Answer 2

Answer:

ok

Step-by-step explanation:

The greatest 5 digit number which will be exactly divisible by 5 , 10, 15 , 20 and 25 is-

We know the greatest number of 5 digits is 99999 . To determine the number we need to divide it by the LCM of the following numbers given in the stem . The Lcm of the numbers is - 300.

99999÷300 = Quotient = 333 and remainder = 99

It is seen from the above that 99999 is not divisible by 300. the remainder is 99.

If dividend is 99 less than 99999, the number will be divisible by 300.

Or if the dividend is (300-99) = 201 more , also then it is divisible by 300.

The number 99999+ 201 is= 100200 which is of 6 digits .

The number of 5 digits divisible by the number will be then . (99999-99)= 99900
