## SI and CI Questions for IBPS PO 2017

[maxbutton id=”30″]

1. The least number of complete years in which a sum of money put at 20% CI will be more than doubled is :

A. 4

B. 5

C. 6

D. 8

A.

Go through Option

1 * (1.2) = 1.2

1 * (1.2)2 = 1.44

1 * (1.2)3 = 1.728

1 * (1.2)4 = 2.0736

Hence minimum 4 years required to double the sum.

2. The difference between CI and SI on a sum of money lent for 2 years at 10% is Rs. 40. The sum is :

A. 1600

B. 3000

C. 4000

D. None of these

C.

Difference between CI and SI for 2 years = P (r/100)2

40 = P (10/100)2 => P = 4000

3. A certain sum amounts to Rs. 8998.8 in two years and to Rs. 9528.128 in three years, at compound interest per annum. What is the principal and rate of interest?

A. Rs.12000,5%

B. Rs.6000,8%

C.Rs.8000, 6%

D. Rs.10000, 8.5%

C.

P( 1+ r/100)3/ P( 1+ r/100)2 = (1+ r/100)

9528.128/8988.8    =  (1+ r/100)

( 1 + 84270/1404500) = (1+ r/100)

(1 + 6/100)     =  (1+ r/100)

r = 6%

8988.8 = P(1+ 6/100)3

P = 8000

4. A titan watch is sold for Rs. 440 cash or for Rs. 200 cash down payment together with Rs. 244 to be paid after one month. Find the rate of interest charged in the instalment scheme :

A. 10%

B. 15%

C. 20%

D. 25%

C

Principal for next month = 440-200 = 240

Amount paid after next month = 244

Therefore interest charged at Rs. 240= 4

4 =  (240*r*1/12*100)  => r = 20% per annum

5. Purnima borrowed a sum of money and returned it in three equal quarterly instalments of Rs. 17576 each. Find the sum borrowed, if the rate of interest charged was 16% per annum compounded quarterly. Find also the total interest charged.

A. 46900 and 4700

B. 48775 and 3953

C. 68320 and 1200

D. None of these

Rate of Interest = 16% annum

Actual rate of Interest = 4% per Quarter

Principal of all three installments

= [ 17576 (25/26) + (25/26)2 + (25/26)3]

=[17576*25*1951/26*676] = 48775

Total amount paid = Rs.17576 *3 = 52728

Interest charged = 52728 – 48775 = 3953

6. Sunidhi borrowed Rs. 10815, which is to be paid back in 3 equal half yearly instalments. If the interest is compounded half yearly at 40/3% per annum, how much is each instalment?

A. 2048

B. 3150

C. 4096

D. 5052

Rate of  Interest = 40/3÷2 % = 20/3% half yearly

10815 = x [ 15/16 + (15/16)2 + (15/16)3]

X= 4096

7. Mr. Lala ram has lent some money to Aaju at 6% p.a. and the Baaju at 8% p.a. At the end of the year he has gain the overall interest at 7% per annum. In what ratio has he lent the money to Aaju and Baaju?

A. 2 : 3

B. 1 : 1

C. 5 : 6

D. 4  : 3

B.

6          8

7

1    :      1

8. The simple interest on certain sum at 5% for 9 month is Rs. 10 greater than the simple interest on the same sum @ 3% for 14 months. What is the sum of interest in both the cases (i.e. – total sum of interest) ?

A. Rs. 130

B. Rs.290

C. Rs. 120

D. Rs. 330

(P*5*9/100*12) – (P*14*3/100*12) = 10

P = Rs. 4000

Now, (4000/100*12)* [5*9 + 14*3] = Rs. 290

9. Mr. Bajaj invested 1/7 of his total investment at 4% and ½ at 5% and rest at 6% for the one year and received total interest of Rs. 730. What is the total sum invested?

A. Rs. 70000

B. Rs.14000

C. Rs. 24000

D. Rs. 38000

Let the Principal be x, then

• [ (x/7)*4 + (x/2)*5 + (5x/14)*6]/100 = 730
• X=14000

10. The compound interest on a certain sum for 2 years is Rs. 756 and SI (simple interest) is Rs. 720. If the sum is invested such that the SI is Rs. 900 and the number of years is equal to the rate per cent per annum, find the rate per cent :

A. 4

B. 5

C. 6

D. 10

CI for 2 years = Rs. 756

SI for 2 years = Rs. 720

It means the Interest on the  interest of the first year = Rs. 36  (756-720)

This implies that the rate of Interest is 10% as 36/360 *100 = 10%

It means the principal for the first year was Rs. 3600

P*10*1/100 =360

P= 3600

Now,         P*k*k/100 = SI

3600*K2/100 = 900

K=5
