1. Answer : 4 Explanation : Let the borrowing of Company A = x Interest of Company A = 234000 Rate of Interest = 18%  ∴x×18100=234000     ⇒x=1300000   Let the borrowing of Company B = y  Interest of Company B = 576000 Rate of interest = 24% ∴y×24100=576000     ⇒y=2400000   Required difference = y - x = 2400000 - 1300000 = Rs. 1100000      2. Answer : 2  Explanation :   Let the profit of Comapny B = 100%  Dividend Payout ratio(%) of B = 19.60  Remaining percent i.e retained earning = 100 - 19.60 = 80.4%  According to question, 80.4% = Rs.402 lakh  100% = Rs.500 lakh  Therefore,  Total dividend paid by Company B = 500 - 402 = Rs. 98 lakh    Let the profit of company D = 100%  Dividend payout ratio (%) of D = 32.50   Remaining percent i.e retained earning = 100 - 32.50 = 67.5%   According to question, 67.5% = Rs. 270 lakh   100% = Rs. 400 lakh  Therefore, Total dividend paid by company D = 400 - 270 = Rs. 130 lakh   Required difference = 130 - 98 = Rs. 32 lakh      3. Answer : 3 Explanation :  Let the profit of Company C = 100%  Dividend payout ratio of C = 8.75%  Remaining percent i.e, retained earning = 100 - 8.75 = 91.25  According to question, 91.25% = Rs. 365 lakh  100% = Rs. 400 lakh  Therefore, Profit of C = Rs. 400 lakh   Let the profit of company E = 100%  Dividend payout ratio of E = 28%  Remaining percent i.e retained earning = 100 - 28 = 72%  According to question, 72% = Rs.216 lakh  100% = Rs.300 lakh Therefore, Profit of E = Rs. 300 lakh  Required percentage = 100400×100 = 25% less     4. Answer : 3  Explanation :   Profit made by company A = Rs. 200 lakh  Profit made by company B = Rs. 500 lakh   Required Sum = 200 + 500 = Rs. 700 lakh      5. Answer : 4  Explanation :   Required Sum = 1300000 + 2400000 + 810000 + 1600000 + 1200000 = 7310000 = Rs. 73.1 lakh

A static variable in Java belongs to its class and its value remains the same for all its instances. A static variable is initialized when the class is loaded by the JVM. If your code tries to access a non-static variable, without any instance, the compiler will complain, because those variables are not created yet and they are not associated with any instance.
