Question 2 is not quite clear. What exactly are you trying to ask?
Assume the cost to be x for the Chef's item, 1.25x for the substituted items.

Total for Day 1+ Day 2 substitute items : 1.25* 20 + 1.25*32.
Is this approach correct?

let me know if helps.

Question 2 is asking asking about the ratio of total amount that was spend by the first day shopper who bought something else instead of Pan (on day 1 and day 2) and total amount that would have been spent if every first day shopper got pan on Day 1.

Assuming Cost of one item as Y and Total Number of First Day Shopper as X

Amount that was spent by First day shopper who bought something else than Pan on Day 1 and Day 2=(X/5+*X/5*23/100))*1.25Y

total amount that would have been spent if every first day shopper got pan on Day 1= X*Y

Ration= ((X/5+*X/5*32/100))*1.25Y)/X*Y=0.33

%=33%

Edit: Changed the % from 23 to 32.

Sorry, still not clear. Sharing with you my solution. Please let me know the errors.

Assuming total people to be 100
Assume price to be 'y'

Question is asking :Total cost spent by people who bought different items. Shouldn't that be 1.25y(20+32)
 
In your solution, you have considered 23. Why? These are the folks who did not make the purchase.

Hence, 65y /100y. 
Where am I going wrong again and again?

shivangishar , let me if it helps.

Sorry It was typo it should have been 32. Thanks for pointing it out.

Your second day calculation is incorrect.

Assuming: 100 People were Day 1 shoppers

1st Day: 20 People bought something other than Pan
 60 People never visited the site again
 20 People Visited the site again on 2nd Day

2nd Day: Base of the calculation will be 20 not 100.As questions give us the data of Day 1 shopper shopper for 3 days. So only 20 people from first day will visit the site on Day 2. Also quoting the line from question for better understanding.

(“For each of the first 3 days of that week, the graph shows the subsequent behaviour of all the Day 1 shoppers who visited Online Retailer X's website seeking ChefZ”)

2nd Day: 32% of 20 People bought something other than Pan
 45% of 20 People never visited the site again
 23% of 20 People Visited the site again on 3nd Day

So now your calculation will become=(20 + 20(32/100))*1.25y=33y

total amount that would have been spent if every first day shopper got pan on Day=100y

So %=33%

Can someone please explain Q1?

Sajjad1994 · Answer

20% of 1st day shoppers revisited the second day, and 23% of those 20% revisited the 3rd day.

0.20*0.23*100= 4.6%

chetan2u · Answer

The most important point:   We are talking of only the first day shoppers. If 100 came on first day, the next day only 20 of them visited the website and the data given on Day 2 is about these 20 shoppers only.1. __ % of Day 1 shoppers visited the site on Day 3.
a) Let the total be 100 on Day 1, so 20% or 20 visited on Day 2.
b) Next day, 23% of 20 visited again, so 4.6
c) Therefore, 4.6% of Day 1 shopper visited on Day 3.
 Answer: Between 2 and 5. 
2. Shoppers at Online Retailer X who purchased substitute items on Day 1 and Day 2 paid a total amount that was approximately __% of the total all Day 1 shoppers would have paid had each of them been able to purchase ChefZ on Day 1.
Day 1: 20, and paid 20*1.25 or 25 units
Day 2: 32% of 20 or 6.4 and paid 6.4*1.25 or 8 units.
Total 25+8 or 33, but it would be 100*1 if all shoppers on Day 1 purchased the product. 
 Answer: 33
