Question

If there are 12apples and third of those is bad ,then how many are bad?




​

Answer 1

Answer:

4 apple will be bad as.!!!.

Answer 2

Answer:

In the twelve apples, every 3rd apple is bad.

This problem can be approached by many ways.

1) Straightforward:

If every 3rd apple is bad of the 12 apples,

12/3 apples are bad.

Hence 4 apples are bad.

2) By using A.P. (Arithmetic Progression):

Let us give a special index to all the apples.

apple_1 = 1

apple_2 = 2

apple_3 = 3

.

.

.

apple_12 = 12

So, every third apple:

apple_3n, where n less than or equal to 12/3 or 4.

Hence,

apple_3, apple_3(2), apple_3(3) and apple3(4) are bad.

Hence 4 apples are bad (the 3rd, 6th, 9th and 12th).

Using A.P., you can actually know which apples are bad.

3) By using multiples of 3:

3n are all the multiples of three.

If we limit n less than or equal to 4, we stay within the limits of 12 apples.

Hence 4 apples are bad.

And there are tons of other ways to do this. Final answer is 4 apples.

Hope this helped.
