SOLUTIONS:

Number of products which are not sold by company R in 2018 = (100 – 46)/100 x 210000 = 54/100 x 210000 = 113400
Number of products which are not sold by company S in 2018 = (100 – 62)/100 x 180000 = 38/100 x 180000 = 68400
Required percentage = 113400/68400 x 100 = 165.78% = 166% approx

Number of products sold by company P in 2018 = 42/100 x 250000 = 105000
Number of products sold by company P in 2017 = 105000 x 80/100 = 84000 Number of products sold by company Q in 2018 = 58/100 x 320000 = 185600
Required ratio = 84000 :185600 = 105 : 232

Number of products sold by company P in 2018 = 42/100 x 250000 = 105000
Number of products sold by company R in 2018 = 46/100 x 210000 = 96600
Number of products sold by company T in 2018 = 54/100 x 150000 = 81000
Required average = (105000 + 96600 + 81000)/3 = 282600/3 = 94200

Number of products sold by company S in 2018 = 62/100 x 180000 = 111600
Number of products produced by company S in 2017 = 111600 x 90/100 = 100440
Total number of products sold by company S in 2017 = 45/100 x 100440 =45198

Number of products sold by company P in 2018 = 42/100 x 250000 = 105000
Number of products sold by company Q in 2018 = 58/100 x 320000 = 185600 (Maximum)
Number of products sold by company R in 2018 = 46/100 x 210000 = 96600
Number of products sold by company S in 2018 = 62/100 x 180000 = 111600
Number of products sold by company T in 2018 = 54/100 x 150000 = 81000

Let, initial amounts invested by Ramesh, Nimo and Bina be Rs.5k, Rs.8k and Rs.3k respectively. Ratio of shares in the profit: Ramesh : Nimo : Bina = (5k x 2 + 10k) : (8k + 12k x 2) : (3k + 6k x 2) = 20k : 32k : 15k = 20 : 32 : 15
Share of Nimo in the profit = [32/(20 + 32 + 15) ]x 134000 = 32/67 x 134000 = Rs.64000

Let, the fraction be p/q. According to the question (p x 120/100)/(q x 95/100) = 6/5 => 120p/95q = 6/5 => p/q = 6/5 x 95/120 => p/q = 19/20
40% of the original fraction is 19/20 * 40/100 = 19/50
