how can we decide What is the percentage of items in the Kids section in the price range $6 to $20?

I don't have any option to calculate the total here unlike other sections, do I? There's no data on the last two price ranges in kids section.
You can calculate the total in the Dress section. We know that the total number of items in the Kids section will be half of it. Then we can find the percentage.

I hope that helped!

chetan2u I am not able to understand this question. Please help

It says "the number of items under each price range is given as % of total items except under one price range". Is it total 100% vertically (for each price range) or horizontally for each item?

The third question is also difficult to understand "Which section has the highest number of items costing more than $100?"

How can we derive at the third one? We would not have a definite value for number of items in kids costing more than 100.

Add up all the % in the Dress section - it comes out to be 72%
That means the remaining 28% of total(x) = 56. So X = 200 items
Kids section has half the number of items, so it has 100 items.
24 out of 100 = 24%

The other questions are also answered the same way, since the kids sections with the given numbers already adds up to 59%
The other two sections of the kids section can be max 41% (if you consider even one of the unknown numbers as 0%)

Hope this helps

A mall has five sections as shown below in the table. The table further gives the distribution of cost of all the items in each section under various price ranges. The cost of each item in the mall is in whole dollars only and at least one dollar. For each section, the number of items under each price range is given as % of total items except under one price range, where the percentage is converted to the actual number.

$1 to $5$6 to $20$21 to $30$31 to $100More than $100
Dress25%27%5615%5%
Cosmetics48%26%15%10%50
Electronics5%16%27%745%
Food12010%10%0%0%
Kids20%2415%Not KnownNot Known

Due to certain errors, the price of items above $30 in the Kids section have not been computed and filled as Not Known. However, it is known that the Kids section has half the number of items that are in the Dress section.

Select Yes if the question can be answered from given info. Otherwise, select No.
1. We need to find which statements can be found using the information in the table.

2. Let’s first try to turn most of the percentages into numbers (of items).

  • Dress: 56 contributes to 100 - (25 + 27 + 15 + 5) = 28%. So, one percent is 2 items.

  • Cosmetics: 50 contributes to 100 - (48 + 26 + 15 + 10) = 1%. So, one percent is 50 items.

  • Electronics: 7 contributes to 100 - (5 + 16 + 27 + 45) = 7%. So, one percent is 1 item.

  • Food: 120 contributes to 100 - (10 + 10) = 80%. So, one percent is 3/2 of an item.

  • Kids: The total number of items in the Dress section is 50+54+56+30+10 = 200. That means the total number of items there is 100. So, one percent is 1 item.

3. Now, we can update our table:

$1 to $5$6 to $20$21 to $30$31 to $100More than $100
Dress5054563010
Cosmetics2400130075050050
Electronics51627745
Food120151500
Kids202415Not KnownNot Known

4. Which section in the mall has the highest number of items? The Kids section has 2 times less items than the Dress section. The Dress, Electronics, and Food sections are much less than the Cosmetics section. So, this statement can be answered.

5. What is the percentage of items in the Kids section in the price range $6 to $20? The percentage of items in the Kids section in the price range $6 to $20 will equal 24/100 or 24%. So, this statement can be answered.

6. Which section has the highest number of items costing more than $100? The Kids section has less than 100-(24+20+15) = 41 items there. This number is less than the 50 items from the Cosmetics section, which is larger than the others too. So, this statement can be answered.
