Total number of domestic products = foreign products = 320/2 = 160
Domestic, Cosmetic, FDA approved products = 160/2 = 80
Foreign products having both approvals = 0
Domestic products having both approvals = 60
Let the number of domestic, cosmetic, both the approvals = x
=> the number of domestic, nutrition, both the approvals = 60 – x
Total number of nutrition products = 140
=> total number of cosmetic products = 320 – 140 = 180
Number of foreign, nutrition products = 70
Let number of foreign, nutrition, FDA products = y
=> number of foreign, nutrition, EU products = 70 – y
Also, number of foreign, cosmetic products = 160 – 70 = 90
Total FDA approved products = 200
Total foreign, FDA approved products = 70
Number of foreign, nutrition, FDA products = y
=> number of foreign, cosmetic, FDA products = 70 – y
=> number of foreign, cosmetic, EU products = 90 – (70 – y) = y + 20
Number of cosmetic, FDA approved products = 120
=> number of nutrition, FDA approved products = 200 – 120 = 80
=> number of domestic, nutrition, FDA approved products = 80 – y
The rest of the given information can be gathered as follows-
Now we can answer the questions
The number of foreign products that were FDA approved cosmetic products = 40










While making the route plan, the supplier goes to the locations in decreasing order of demand and if the last location is Ahmednagar, then it must have least demand (50 units)
So, the supplier must have supplied the order in the following manner-
C (70 or 100 units) > B (60 units) > D (50 units) ≥ A (50 units)
The total distance (minimum) covered W – C – B – W – D – W – A
= 12 + 4 + 10 + 2 + 2 + 5 = 35 km
Tohri’s success rate was twice that of Lahur’s on the first day,
=> n/(h – 15) = 2 × (50/h)
Solving, nh = 100h – 1500
Also, Tohri’s success rate was 75% of Lahur’s on the second day,
=> (100 – n)/h + 15) = (75/100) × (50/h)
Solving, 200h – 2nh = 75h + 1125
Substituting the value of nh,
=> 200h – 2(100h – 1500) = 75h + 1125
=> 3000 = 75h + 1125 => h = 25
Substituting again,
25n = 2500 – 1500 = 1000 => n = 40
Now we can answer the questions
The number of TRICCEK items sold by Tohri on the first day = 40
