DIVISIBILITY BY 25

Divisibility by 25 :

If the last two digits of a numbers are 00, 25, 50 or 75 is divisible by 25.

Divisibility Test is the topic in which we are going to see the shortcuts to predict one number is divisible by another number with out doing too much calculation.

Once we remember these rules we can easily divide two numbers without calculator.

Example 1 :

Check 3500 is divisible by 25.

Solution :

• To check whether the given number is divisible by 25, we have to see the last two digits.
• If the last two digits are either 00 or 25 or 50 or 75 then the given number is divisible by 25.
• The given number is 3500.
• The last two digit is 00.
• So the given number 3500  is divisible by 25.

Example 2 :

Check whether 7520 is divisible by 25.

Solution :

• To check whether the given number is divisible by 25, we have to see the last two digits.
• If the last two digits are either 00 or 25 or 50 or 75 then the given number is divisible by 25.
• The given number is 7520.
• The last two digit is 20.
• So the given number is not divisible by 25

Example 3 :

Check whether 8550 is divisible by 25.

Solution :

• To check whether the given number is divisible by 25, we have to see the last two digits.
• The given number is 8550
• The last two digits is 50.
• So the given number 8550 is divisible by 25.

Example 4 :

Check whether 1025 is divisible by 25.

Solution :

• To check whether the given number is divisible by 25, we have to see the last two digits.
• The given number is 1025
• The last two digits is 25.
• So the given number 1025 is divisible by 25.
