Question 1 of 5
1. Question
Difference between total CI and total SI on a certain sum at 20% per annum for 2 years is Rs 840. What will be the simple interest earned on same sum at 25% per annum for 3 years?
Correct
Answer: (a) 15750
Explanation:
CI-SI =for two years=p*(r/100)2 =840
=p*20/100 *20/100=840
On solving we get, P=21000
SI for 21000=21000*25/100*3=15750
Incorrect
Answer: (a) 15750
Explanation:
CI-SI =for two years=p*(r/100)2 =840
=p*20/100 *20/100=840
On solving we get, P=21000
SI for 21000=21000*25/100*3=15750

Question 2 of 5
2. Question
Difference of the compound interest received in first year and second year at 20% per annum at CI is Rs 2400 then find the sum?
Correct
Answer: (a) 60000
Explanation:
Let the sum be=Rs 100x
CI in first year=Rs=20x
CI in two years=44% of 100x=Rs. 44x
Compound interest in second year =44x-20x=24x
ATQ
24x-20x=2400
X=600
Required sum=Rs.60000
Incorrect
Answer: (a) 60000
Explanation:
Let the sum be=Rs 100x
CI in first year=Rs=20x
CI in two years=44% of 100x=Rs. 44x
Compound interest in second year =44x-20x=24x
ATQ
24x-20x=2400
X=600
Required sum=Rs.60000

Question 3 of 5
3. Question
Samarth invested Rs.75000 in a scheme offering R% p.a. SI for 5 years and Rs.50000 in another scheme offering 12%p.a. Cl compounding annually for 2 years. If difference in 2nd year Cl and 2nd year SI is Rs.2220, then find value of R%.
Correct
Answer: (d) 6%
Explanation:
2nd year CI=(50000(1+12/100)2 -50000)-(50000*12/100)
=12720-6000=6720
Now second year SI =6720-2220=Rs. 4500
Now R=4500/75000 *100 = 6%
Incorrect
Answer: (d) 6%
Explanation:
2nd year CI=(50000(1+12/100)2 -50000)-(50000*12/100)
=12720-6000=6720
Now second year SI =6720-2220=Rs. 4500
Now R=4500/75000 *100 = 6%

Question 4 of 5
4. Question
The difference between total SI earned on Rs. ‘P’ at 12% p. a for 3 years and total Cl earned on same sum at 15% p. a for 2 years when compounded annually is Rs.750 Find P? (in Rs.)
Total SI=P*12*3/100=36P/100 Rs.
Correct
Answer: (a) 20000
Explanation:
Effective rate of interest for CI at 15% p. a compounding annually for 2 years
=15+15+(15*15)/100 =32.25%
Total CI=P*32.25P/100 Rs.
ATQ, 36P/100 -32.25P/100 =750
P=20000
Incorrect
Answer: (a) 20000
Explanation:
Effective rate of interest for CI at 15% p. a compounding annually for 2 years
=15+15+(15*15)/100 =32.25%
Total CI=P*32.25P/100 Rs.
ATQ, 36P/100 -32.25P/100 =750
P=20000

Correct
Answer: (a) 5120
Explanation:
Difference between CI and SI for 2 years=PR2 /1002
Here difference =Rs. 20, R=25/4 % per annum
20=P*[25/4*100]2 =5120
Incorrect
Answer: (a) 5120
Explanation:
Difference between CI and SI for 2 years=PR2 /1002
Here difference =Rs. 20, R=25/4 % per annum
