It takes 3 hours to type 6 memos. how long will it take to type 48 memos?

24 hours.

Step-by-step explanation:

We will solve this problem by unitary method.

∵ Time taken to type 6 memos = 3 hours

∴ Time taken to type 1 memos = hours

∴ Time take to type 48 memos = × 48

                                                 = ×  48

                                                 = 24 hours

It will take 24 hours to type 48 memos.
