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 step by step, let's denote the total number of camels in the herd as \( N \).

### Step 1: Set up the equation based on the problem statement
According to the problem:
- One fourth of the herd was seen in the forest: \( \frac{1}{4}N \)
- Twice the square root of the herd went to the mountains: \( 2\sqrt{N} \)
- The remaining camels were seen on the bank of a river: 15 camels
