3. By the puddle, the squad In twos, in threes, in fours

Of long-legged tadpoles, No matter how the commander arranged,

Formed a very neat column: There was always someone left over

Exactly five in every row. In any group of five.

Now everyone is happy, everyone is delighted!

But how many tadpoles are there in total, not just in the rows?

Do your calculations with the right aim.

Note. Remember that there are fewer than 10 rows in the tadpole column.
3. The desired number, when divided by 2, 3, and 4, each time gives a remainder of 1, but is divisible by 5. LCM $(2,3,4)=3 \cdot 4=12$, but the number $12+1=13$ is not divisible by 5. However, the number $12 \cdot 2+1=25$ is the smallest number that satisfies the condition. Since the number of rows is less than 10, there were 25 tadpoles (5 rows).
