578 business and personal emails there are 30 fewer personal emails so how many personal emails

Personal emails = 274 emails.

Step-by-step explanation:

Given,

Business and personal emails = 578

Therefore, there are two types of emails. Again, there are 30 fewer emails in personal emails.

The total number of emails after deducting the fewer personal emails = (578 - 30) = 548 emails.

Therefore, each type of email, according to the question = (548/2) = 274 emails

So, personal emails are 274. Business emails = (274 + 30) = 304 emails.
