Option A Let the rate of interest =R%. Then 5000 * 2* R / 100 + 3000 * 4* R /100 = 4400 100R+120R= 4400 =>220R= 4400 =>R= 20%
A and B borrows Rs.5000 and Rs.3000 respectively at the same rate of interest for 2 ½ years. If B paid Rs.200 more interest than A, Find the rate of interest.

Option B From the question, 5000 * 5*R/ 100*2 – 3000 * 5 * R / 100*2 = 200 ( 2 ½ = 5/2) =>10000 R/ 200 =200 =>R= 4%
The simple interest on a sum of money 3 years is Rs. 240. And the compound interest on the same sum at the same rate for 2 years is Rs.170.What is the rate of interest?

22.9
Option A Simple interest for 1 year = 270/3= 90 =PR/100 For two years= 90*2= Rs.180 Difference for 2 years= 180- 160 = Rs.20 Difference between C.I and S.I = PR2 /1002 Rate % = 20/90 * 100 =22.2%

Option C Let Principal=P. =>Amount = 2P Simple interest = 2P-P= Rs.P SI= P*R*T/100 P= P*5 *T/2*100 =>200 = 5T T= 200/5= 40 years.
A person gave Rs.4000 for 3 years to his friend and gave Rs. 5000 for 4 years to his brother at the same rate of simple interest. Finally he receives Rs.1600 as interest from both ,What is the rate of interest per annum?

Option D Let the rate of interest = x% 4000 * x * 3/ 100 + 5000 * x*4 /100 = 1600 120x + 200x = 1600 =>320x= 1600 =>x= 5%
A person borrowed some amount at the rate of 12% per annum at simple interest .After 5 years 4 months , he paid Rs.720 as an interest .Find the amount borrowed by him?
Rs.1235
Rs.1125
Rs.1254
Rs.1200
Rs.1300
Option B R= 12%, T= 6 years 8months. 5 years 4 months =5 4 /12 = 5 1/3 = 16/ 3 years. Interest =PRT/ 100 720 =P *12*16/ 100 *3 =>P=Rs. 1125
A deposits Rs. 20,000 as fixed deposits at a bank at the rate of 10% per annum simple interest. But for some reasons he has to withdraw the entire money after 2 years .

Option C Principal= Rs. 20,000 Rate%= 10% SI for 5 years= 20000*10 *5/100 =Rs.10,000 After three years interest received = 10000-4000= Rs.6000 Rate%= 6000/ 12000 * 100/2 = 25%
Sonu deposits Rs.2500 in 2 years. She receives 4% compound interest for the first year. Second year the bank hikes its interest rate as 8%.Find the difference of the amount she received in the two years.

Option A P= Rs.2500 R1= 4%, R2=8% Amount for first year = 2500 ( 1+ 4/100) =Rs.2600 Second year= 2600 (1+8/100)= Rs.2800 Difference = 2800- 2600 = Rs. 200
Man invests ½ of his retirement amount at 2% in one bank and 1/5 amount at 5% in the second bank and 1/8 th amount in the third bank at 8% .If simple interest of 2 years amount he got is Rs.10,000, Find the total amount he invested?
Rs.176,099
Rs.1,66,667
Rs.1,76,900
Rs.1,23,765
Rs.1,89,002
Option B Let the sum be Rs.100. SI = (100/2 * 2/100 * 2) +( 100/5 * 5/100 *2) + ( 100/8 * 8/100* 2) = 6 Actual Sum = 10000/6 * 100 =Rs.1,66,667
Arun invests sum amount in the compound interest at 25 % for 5 years. At the end of five years he got Rs.2500 as an interest amount. If he invests in simple interest then what will be the interest amount on same sum for same period and rate
Rs.2300
Rs.2000
Rs.1200
Rs.2040
RS.1600
Option B C.I = P ( ( 1+25/100)2 – P) = 25P/16 Given C.I = Rs2500 P=Rs. 1600 S.I = 1600 * 25*5/100 =>S.I= Rs.2000
