Hint: Use the unitary method to find the answer. First find the number of words he can write in 1 minute. Then multiply this by 10 to find the number of words he can write in 10 minutes.

Complete step by step solution:

We know that he can write 20 words in one hour.

We also know that one hour consists of 60 minutes.

This means that Mohan is able to write 20 words in 60 minutes.

20 words $\to $60minutes

We will now find the number of words he can write in 1 minute.

For this, we will divide the known number of words with the known measure of time.

So, he can write $\dfrac{20}{60}$ i.e. $\dfrac{1}{3}$ words in a minute.

We now need to find the number of words he can write in 10 minutes.

For this, we will multiply 10 and the number of words he can write in one minute.

So, the number of words he can write in 10 minutes is:

$10\times \dfrac{1}{3}=3.33$ words.

Hence, Mohan can write 3.33 words in 10 minutes.

Note: We can solve this question using another method also. We need to find the number

of words he can write in 10 minutes. We know that he can write 20 words in 60 minutes.

Also 10 minutes is one-sixth of 60 minutes. So, we can divide 20 words by 6 to get 3.33 as

the final answer which is the same as obtained above.
