Question

Choose the number which is divisible by both 4 and 5.

• A. 240
• B. 145
• C. 230
• D. 144

Answer 1

The correct option is A

240

For a number to be divisible by 4, the last two digits of a number should be divisible by 4, In 240, we have 40 is divisible by 4, hence 240 is divisible by 4.

For a number to be divisible by 5, the last digit of the number should be either 0 or 5, hence it is divisible by 5.

Other numbers: 145, is not divisible by 4 but divisible by 5.
230 is not divisible by 4 but divisible by 5.
144 is divisible by 4 but not by 5.
