Need explanation for Journal entry

While solving one question about Journal entries, I came across this question:

 

My doubt is, rather than doing the Journal entry as given, can't we do it directly? Like this way:

Bank A/c ----------> 50,000 (Dr.)

To Fire Premium A/c ---------> 10,000

To Motor Premium A/c -------> 30,000

To Marine Premium A/c  -----> 10,000

 

What is the difference between both methods?
