Accepted Answer

We can apply the formula to calculate the interest amount I = P x R x t where A = Total Accrued Amount (principal + interest) P = Principal Amount I = Interest Amount R = Rate of Interest per year as a percent; t = Time Period involved in years For Company A in 2006, Principle amount = 10000 Rate of interest = 11.5 % ( As per given graph for company A in 2006) Time = 1 year The interest amount received by Samir in 2007 I = P x R x t The interest amount received by Samir in 2007 = 10000 x 11.5 x 1/100= 10000 x 115 x 1/10 x 100 = 10 x 115 = 1150 Total amount received by Samir in 2007 = Interest amount + Principal amount = 10000 + 1150 = 11150 Again For Company A in 2007, Principle amount = 11150 Rate of interest = 15 % ( As per given graph for company A in 2007) Time = 1 year The interest amount received by Samir in 2008 I = P x R x t The interest amount received by Samir in 2008 = 11150 x 15 x 1/100 = 1115 x 15/10 = 1115 x 3/2 = 3345/2 = 1672.5 Total amount received by Samir in 2008 = Interest amount + Principal amount = 11150+ 1672.5 = 12822.50 Hence, their interest = 12822.50 - 10000 = 2822.50 For Company B in 2006, Principle amount = 10000 Rate of interest = 13.5 % ( As per given graph for company B in 2006) Time = 1 year The interest amount received by Samir in 2007 I = P x R x t The interest amount received by Samir in 2007 = 10000 x 13.5 x 1/100= 10000 x 135 x 1/10 x 100 = 10 x 135 = 1350 Total amount received by Samir in 2007 = Interest amount + Principal amount = 10000 + 1350 = 11350 Again For Company B in 2007, Principle amount = 11350 Rate of interest = 14 % ( As per given graph for company B in 2007) Time = 1 year The interest amount received by Samir in 2008 I = P x R x t The interest amount received by Samir in 2008 = 11350 x 14 x 1/100 = 1135 x 14/10 = 1135 x 7/5 = 227 x 7 = 1589 Total amount received by Samir in 2008 = Interest amount + Principal amount = 11350+ 1589 = 12939 Since, their interest = 12939 - 10000 = Rs. 2939 Hence, difference between the interests earned = 2939 - 2822.50 = Rs. 116.50 If Samir had invested the amount in company B for both years then he would get Rs. 116.50 more.

Question 20

An amount of Rs. 20,000 was invested in Company 'B' in 2008 and after one year the entire amount along with interest was will be reinvested in the Company A for one more year. What will be total amount of interest accrued?

Accepted Answer

Simple interest formula I = P x R x T where P is the Principal amount of money to be invested at an Interest Rate R% per period for T Number of Time Periods. Interest received in 2009 from Company B = 20000 x 145 x 1/100 = 2900 Hence, their amount = 20000 + 2900 = Rs. 22900 Interest will be received in 2010 from company A = 22900 x 12.5 x 1/100 = Rs. 2862.50 Hence, total amount of interests for both years = 2900 + 2860.50 = Rs. 5762.50
