One fourth of a herd of camels was seen in the forest. Twice the square root of the herd had gone to mountains and the remaining 15 camels were seen on the bank of a river. Find the total number of camels.

Explanation

To solve the problem, let's denote the total number of camels in the herd as \( x \).

### Step 1: Set up the equation based on the information given.
According to the problem:
1. One fourth of the herd was seen in the forest: \( \frac{x}{4} \)
2. Twice the square root of the herd had gone to the mountains: \( 2\sqrt{x} \)
3. The remaining camels seen on the bank of the river are 15.
