Answer 2

Concept

Divisibility means a property of a number that it is coming in the table of another number.

Given

Oliver doesn't have more than 30 toys.

To find

total number of toys that Oliver have?

Explanation

First we have to find the numbers less than 30 when divided by 4 gives remainder as 3. These are 23,19,15,11,7.

Now we have to find the numbers which when divided by 3 gives 2 as remainder among  23,19,15,11,7. These are 23,11 only.

Now we have to find that number which when divided by 5 gives 3 as remainder. This is 23.

Hence Oliver have 23 toys.
