Detailed explanation-1: -When you rub both balloons, both end up with negative charge. Similar charges repel so the balloons push away from each other. You can even use one balloon to push the other around!

Detailed explanation-2: -They repel each other because the nature of charge on one balloon is opposite from the other.

Detailed explanation-3: -The only way that two objects can repel each other is if they are both charged with the same type of charge. Thus, the repulsion of the balloons provides conclusive evidence that both balloons are charged and charged with the same type of charge.

Detailed explanation-4: -A charged balloon is repelled by another charged balloon because both carry same charges and we know same charges repel each other. Whereas, an uncharged balloon is attracted by charged balloon because unlike charges attract each other.

Detailed explanation-5: -English. When you rub a balloon with a wool cloth, the balloon captures electrons from the wool, leaving the balloon with a negative charge and the wool with a positive charge. If both balloons are rubbed with wool, they will both have same charge (negative) and therefore will repel each other.
