Question: How many foreign products were FDA approved cosmetic products?
Explanation:
There were equal numbers of domestic and foreign products.
∴ There will be 160 foreign as well as domestic products.
Half of the domestic products were FDA approved cosmetic products.
∴ 80 products are domestic, FDA approved and cosmetic products.
None of the foreign products had both the approvals while 60 domestic products had both the approvals.
There were 140 nutrition products, half of them were foreign products.
∴ Number of cosmetic products = 320 – 140 = 180
There were 200 FDA approved products, 70 of them were foreign products
FDA approved products = FDA foreign + FDA domestic
⇒ 200 = 70 + (60 + only FDA domestic products)
⇒ only FDA domestic products = 70
and 120 of them were cosmetic products.
FDA approved cometic products = FDA approved foreign cosmetic + FDA approved domestic cosmetic
⇒ 120 = (0 + only FDA approved cosmetic foreign products) + 80
⇒ only FDA approved cosmetic foreign products = 40
Since there are total 70 foreign FDA approved products out of which 40 are only FDA approved cosmetic foreign products, hence approved nutrition foreign products = 70 – 40 = 30.
⇒ only EU approved nutrition foreign products = 70 – 30 = 40
Total foreign products = 160
⇒ only EU approved cosmetic foreign products = 160 – 40 – 30 – 40 = 50
Total Cosmetic products is 180 = cosmetic foreign + cosmetic domestic
⇒ 180 = (50 + 0 + 40) + (only EU approved domestic cosmetic products + 80)
⇒ only EU approved domestic cosmetic products = 10
Total domestic products = 160 = (10 + only EU nutrition domestic products) + 60 + 70
⇒ only EU nutrition domestic products = 20
With the given information we can tabulate this much.
∴ Number of foreign FDA approved cosmetic products = 0 + 40 = 40
Hence, 40.
