10%
15%
14%
20%
25%
Option B 945 = PR^2/100^2 945 = 42000 * R^2/10000 R^2 = 225 R = 15%
Rohit borrows rs.4000 at 10% on compound interest and at the end of the every year he paid rs.1000 back. How much amount should he pay at the end of the 3rd year to settlement all his debt ?
2500
3000
3240
3014
2480
Option D total amount at the end of the 1st year = 4000 * 110/100 = 4400 After he paid rs.1000, remaining amount = 4400 – 1000 = 3400 total amount at the end of 2nd year = 3400 * 110/100 = 3740 After he paid rs.1000, remaining amount = 3740 – 1000 = 2740 total amount at the end of 3rd year = 2740 * 110/100 = 3014 At the end of 3rd year he paid 3014 to settlement his debt.
A man borrows rs.8000 for 3 years and he gave at 15%, 20% and 30% rate of interest for 1st year, 2nd year and 3rd year respectively. Then how much amount he paid at the end of 3rd years in compound interest ?

14352
17250
19540
20450
Option B Amount in 1st year = 8000 + (8000*15/100) = 9200 Amount in 2nd year = 9200 + (9200*20/100) = 11040 Amount in 3rd year = 11040 + (11040 * 30/100) = 14352
What is the compound interest on rs.8600 at 20% p.a. for 1 years, compounded half yearly.
2240
2420
1440
1806
1425
Option D Rate of interest for 1 year = 20% rate of interest for half year = 10% by applying successive, 10 + 10 + 10 * 10/100 = 21% compound interest = 8600 * 21/100 = 1806
Shivam invested a certain amount at the rate of 14% for 4 years in simple interest and after 4 years he obtained a total simple interest of rs.5600. If invested the same amount at the same rate of interest for 2 years in compound interest then how much interest would he have obtained ?
3220
2996
2834
2450
2830
Option B Let principal be rs. x = x * 14/100 * 4 = 5600 x = 5600 * 100/56 = 10000 by applying successive, rate of compound interest = 14 + 14 + 14 * 14/100 = 19.96% compound interest = 10000 * 29.96/100 = 2996
The difference between simple interest and compound interest on a certain sum at 20% rate of interest for 2 years is 500. What is difference between simple interest and compound interest for 1st year, if interest is compounded half-yearly ?
120
180
125
150
190
Option C 500 = PR^2/100^2 500 = P * 400/10000 P = 12500 simple interest for 1st year = 12500 * 20/100 = 2500 Rate of interest for compound half yearly = 20/2 = 10% by apply successive method, rate of CI = 10 + 10 + 10 * 10/100 = 21% compound interest = 12500 * 21/100 = 2625 Difference = 2625 – 2500 = 125
On a certain sum of money simple interest occurred after 4 years is rs.4800 and compound interest occurred after 2 years is rs.2580. If rate of interest in both cases are same, find the principal amount ?
12000
8000
14000
18000
20000
Option B SI after 4 years = 4800 SI for 1 year = 4800/4 = 1200 SI for 2 years = 2400 CI for 2 years = 2580 by applying SI and CI ratio formula, SI/CI = 200/200 + r 2400/2580 = 200/200 + r r = 15% Let principal = rs. x x * 15/100 * 4 = 4800 x = 4800*100/60 = 8000
What is difference between compound interest and simple interest for 2 years at the rate of 20% on a principal of rs.8500 ?
240
520
340
624
125
Option C SI for 2 years = 8500 * 20/100 * 2 = 3400 by applying successive rate of compound interest after 2 years = 20 + 20 + 20 * 20/100 = 44% CI = 8500 * 44/100 = 3740 Difference = 3740 – 3400 = 340
If a money get tripled in 5 years on a certain rate of simple interest, then find the rate of interest ?
20%
40%
48%
45%
25%
Option B let principal = rs. x amount = 3 * x = 3x simple interest = 3x – x = 2x 2x = x * R/100 * 5 R = 40%
Shiva invested rs. X for 4.5 years at the rate of 20% p.a. on simple interest. If he received rs.2520 as interest, then what is the value of X ?

907892 332898Hi! Do you know if they make any plugins to safeguard against hackers? Im kinda paranoid about losing everything Ive worked hard on. Any ideas? 614432
Nice post. I learn something totally new and challenging on sites I stumbleupon on a daily
basis. It’s always exciting to read content from other authors and use something from their sites.
Today, I went to the beach front with my children. I found a sea shell and gave it to my
4 year old daughter and said “You can hear the ocean if you put this to your ear.” She put the shell to her ear and screamed.
There was a hermit crab inside and it pinched her ear.
She never wants to go back! LoL I know this is totally off topic but I
had to tell someone!
