Investment ratio of A, B & C = (4000 ×6+3000×9):(5500 ×6+4000×9):4
Let A?s investment be= 7a
Let B?s investment be= 6a
Let C?s investment be= 5a
Their investment in 2ndyear:= (125% of 7a): (120% of 6a) : (115% of 5a) = 175 : 144 : 115
Clearly, If 60 % is equally divided then remaining 40% of total profit will be divided between 2 persons A and B in ratio of (profit of A) : (profit of B)= 12,500 : 8500 = 125 : 85 = 25:17
now difference in amount = 25-17 = 8 this difference = 240
therefore 40% of total profit = 240*(25+17)/(25-17) = 1260
? 100% profit = 1260 / 40 × 100 = 3150
Amount invested in savings scheme Q= Rs (8000-X)
Compounding 30 % for 2 years , rate
30+30+ (30*30)/100= 69 %
60 % of X-69 % of (8000-X)=930
X= 5000
In savings savings scheme Q = 8000-5000=3000
5000 - 1500 = 3500
Difference =3500-3000=Rs 500
