Answer:  A. Wed to Fri

We have a bunch of natural numbers and we're told a pair is in the ratio 2:5.

For natural numbers to have this ratio, the left number will be a multiple of two and the right number will be a multiple of five.

Our only option for a multiple of 5 is 15, Friday.  So we have

2:5 = x:15

and x = 15*2/5 = 6

which was Wednesday's number.  So we get Wed:Fri=6:15=2:5.

Answer:

A

Step-by-step explanation:

Let's try each of the answer choices:

A. Wednesday to Friday

On Wednesday, 6 computers were sold and on Friday, 15 were sold. Then we can write 6 : 15, which simplifies to 2 : 5, which matches what we want. So, A is correct.

B. Monday to Thursday

On Monday, 8 computers were sold and on Thursday, 16 were sold. Then we can write 8 : 16, which simplifies to 1 : 2, which does not match what we want. So, B is incorrect.

C. Tuesday to Friday

On Tuesday, 12 computers were sold and on Friday, 15 were sold. Then we can write 12 : 15, which simplifies to 4 : 5, which also does not match what we want. So, C is incorrect.

D. Thursday to Tuesday

On Thursday, 16 computers were sold and on Tuesday, 12 were sold. Then we can write 16 : 12, which simplifies to 4 : 3, which still does not match what we want. So, D is incorrect.

The answer is thus A.
