# Find Out Total Number of Marbles

I have x marbles. My elder brother has 3 more than mine, while my younger brother has 3 less than mine. If the total number of marbles is 15, the number of marbles that I have is

- 3
- 5
- 8
- 7

**Answer: (2) 5**

**Explanation:-**

I have marbles = X

My elder brother has 3 more than mine,

Then, X + 3

My younger brother 3 less than mine,

Then, X – 3

The total number of marbles = X + X + 3 + X – 3 = 15

3 X = 15

X = 5

Hence, I have 5 marbles.
