Answer 3

To solve this problem, you can set up an equation. Let's use "x" to represent the number of stacks the boy had before.

1. The boy gives away a third of his stationery to a friend, which means he has 2/3 of the original amount left.
2. He also gives 6 stacks to his brother.
3. After these two actions, he has 12 stacks left.

So, you can set up the equation as follows:

(2/3)x - 6 = 12

Now, you need to isolate "x" on one side of the equation. First, add 6 to both sides:

(2/3)x = 12 + 6 (2/3)x = 18

Now, to solve for "x," you can multiply both sides by 3/2 to get rid of the fraction:

x = 18 * (3/2) x = 27

So, the boy had 27 stacks of stationery before he gave a third to his friend and 6 to his brother.
