Structured Table with Remarks

Understanding the set :- 1) This set gives us information regarding 320 products of a speciality supermarket 2) Products are further classified into cosmetic product or a nutrition product 3) Also, these products are divided as - foreign product or a domestic product 4) Further, Each of these products had at least one of the two approvals - FDA or EU. This is a question where you will find one data (320 products) being divided into different unrelated divisions (cosmetic, foreign , e.t.c) In might be a bit complex to put all the data into a single table. Therefore, when you come across a question like this, you can make a chart like table where on the top will be the main data (320 products) and then further column or rows will consist of it's divisions. —-- Structured Table with Remarks

Total (320)	Domestic (160)	Cosmetic	only EU
			only FDA
			Both
		Nutrition	only EU
			only FDA
			Both
	Foreign (160)	Cosmetic	EU
		Cosmetic	FDA
		Nutrition	EU
		Nutrition	FDA

Using clue 1, There were equal numbers of domestic and foreign products. => Domestic= foreign = 160 products —-- Structured Table with Remarks

Total (320)	Domestic (160)	Cosmetic	only EU
			only FDA	Total FDA = 80
			Both
		Nutrition	only EU
			only FDA
			Both
	Foreign (160)	Cosmetic	EU
		Cosmetic	FDA
		Nutrition	EU
		Nutrition	FDA

Clue 2 says, Half of the domestic products were FDA approved cosmetic products. => half of 160 = 80 were FDA approved cosmetic products —-- Structured Table with Remarks

Total (320)	Domestic (160)	Cosmetic (90)	only EU
			only FDA	Total FDA = 80
			Both
		Nutrition (70)	only EU
			only FDA
			Both
	Foreign (160)	Cosmetic (90)	EU
		Cosmetic (90)	FDA
		Nutrition (70)	EU
		Nutrition (70)	FDA

Using clue 4, There were 140 nutrition products, half of them were foreign products. => Foreign nutrition = domestic nutrition = 70 => Foreign cosmetic products = 160 - 70 = 90 => Domestic cosmetic products = 160 - 70 = 90 —-- Structured Table with Remarks

Total (320)	Domestic (160)	Cosmetic (90)	only EU
			only FDA	Total FDA = 80
			Both
		Nutrition (70)	only EU
			only FDA	Total FDA = 50
			Both
	Foreign (160)	Cosmetic (90)	EU
		Cosmetic (90)	FDA
		Nutrition (70)	EU
		Nutrition (70)	FDA

Using clue 5, There were 200 FDA approved products. 70 of them were foreign products and 120 of them were cosmetic products. If 70 are foreign products, remaining 130 should be domestic products. In domestic products, FDA approved cosmetic products are 80. =>FDA approved nutrition products are 130-80, i.e. 50 —-- Structured Table with Remarks

Total (320)	Domestic (160)	Cosmetic (90)	only EU
			only FDA	Total FDA = 80
			Both
		Nutrition (70)	only EU
			only FDA	Total FDA = 50
			Both
	Foreign (160)	Cosmetic (90)	EU	50
		Cosmetic (90)	FDA	40
		Nutrition (70)	EU
		Nutrition (70)	FDA

Continuing with clue 5, There are 120 FDA approved cosmetic products. =>Domestic, cosmetic and FDA approved = 80 => Foreign, cosmetic and FDA approved is 120-80, i.e. 40 => EU, cosmetic, foreign product = 90 - 40 = 50 —-- Structured Table with Remarks

Total (320)	Domestic (160)	Cosmetic (90)	only EU
			only FDA	Total FDA = 80
			Both
		Nutrition (70)	only EU
			only FDA	Total FDA = 50
			Both
	Foreign (160)	Cosmetic (90)	EU	50
		Cosmetic (90)	FDA	40
		Nutrition (70)	EU	40
		Nutrition (70)	FDA	30

Now, There are 70 FDA approved foreign products. This implies Foreign, nutrition and FDA approved is 70-40, i.e. 30 => EU ,nutrition, foreign product = 70 - 30 = 40 —-- Structured Table with Remarks

Total (320)	Domestic (160)	Cosmetic (90)	only EU	10
			only FDA	Total FDA = 80
			Both
		Nutrition (70)	only EU	20
			only FDA	Total FDA = 50
			Both
	Foreign (160)	Cosmetic (90)	EU	50
		Cosmetic (90)	FDA	40
		Nutrition (70)	EU	40
		Nutrition (70)	FDA	30

Domestic and Cosmetic = 90 Domestic, cosmetic and FDA approved = 80 This implies, Domestic, cosmetic and FDA not approved is 90-80, i.e. 10. Therefore, (domestic, cosmetic and only EU) = 10 Similarly, we get (domestic, nutrition and only EU) = 70-50 = 20
