Class 10 Banking Important Questions and Answers

Q1. Mr. Raj gets ₹ 7,688 at the end of one year at the rate of 12% per annum in a recurring deposit account. Find the monthly installment.
Options
(a) ₹ 500
(b) ₹ 600
(c) ₹ 700
(d) ₹ 800

Ans. (a) ₹ 600
Explanation:
MV=P×n+P×\frac{n(n+1)}{2×12}×\frac{r}{100} \\ \Rightarrow 7,668=P\begin{pmatrix} 12+\frac{12×(12+1)}{2×12}×\frac{12}{100}\end{pmatrix} \\ \left[\because n=1 \space \displaystyle{year}=12\space \displaystyle{months} \right] \\ ⇒ 7,668=P\begin{pmatrix} 12+\frac{78}{100}\end{pmatrix} \\ \Rightarrow 7,668=P\begin{pmatrix} 12+\frac{1,278}{100}\end{pmatrix}\\ ⇒ P = 600

Q2. A bank offered a scheme of investing ₹ x per month for 2 years. If the rate of interest offered by the bank is 10% p.a. and the total interest received will be ₹ 1,900, then the value of x is
Options
(a) ₹ 700
(b) ₹ 750
(c) ₹ 760
(d) ₹ 800

Ans. (d) ₹ 760

Explanation:
we have 
P = ₹ x, n=2 years = 24 months, r = 10% and 
I = ₹ 1,900
We know,
I = P × \frac{n(n+1)}{2×12}×\frac{r}{100} \\ ⇒  1,900 \\ = x × \frac{24×25}{24} × \frac{10}{100}\\ ⇒  1,900 =  2.5 x
⇒  x = 760.

Q3. Mohan has a recurring deposit account in a bank for 2 years at 6% p.a. simple interest. If he gets  ₹ 1200 as interest at the time of maturity, find :
(a) the monthly installment
(b) the amount of maturity.

Explanation:
(a) Since, number of months (n) = 24 and rate of interest (r) = 6%
I = P ×\frac{n(n+1)}{2×12} × \frac{6}{100} \\ ⇒ 1200 = P × \frac{24(24+1)}{2×12} × \frac{6}{100} \\ ⇒  P = \frac{24(24+1)}{2×12} × \frac{6}{100}\\ = ₹ 800
∴ Monthly instalment = ₹ 800 Ans.
(b) Sum deposited = ₹ 800 × 24
= ₹ 19200
Amount on maturity = ₹ 19,200 + ₹ 1,200
= ₹ 20,400 Ans.

Q4. Anu has a cumulative deposit account in a bank for 5 years at 9% p.a. At the time of maturity, she gets ₹ 51607.50. Find the monthly installment.

Explanation:
we have,
n = 5 year = 5 × 12 = 60 months, r = 9% M.V. = ₹ 51607.50.
Since,
I = P× \frac{n(n+1)}{2×12} × \frac{r}{100} \\ = P × \frac{60×61}{2×12} × \frac{9}{100} \\ = \frac{549P}{40} \\ ∴ M.V. = Pn + I \\ = P  × 60+ \frac{549P}{40} \\ = \frac{2400+549P}{40} \\ = \frac{2949P}{40} \\ \text{According to the question,} \\ =\frac{2949P}{40} \\ = 51607.50 \\ ⇒ P =\frac{51607.50×40}{2949} ∴ P = ₹ 700.

Q5. Government-owned banks have security assured over the investments made by the customers, while private banks provide better services and rate of interest to attract customers. A retired manager from Punjab National Bank, Mr Ranajit Bhattacharya invests in a recurring deposit scheme in IDBI bank with ₹ 10000/-for 6 years and receives ₹ 8,84,250/-. His friend Lt. Colonel Jayant Paranjpe invested in a similar recurring deposit scheme with Punjab National Bank with ₹ 10000/-for 6 years and receives ₹ 19,710/- less than Mr Ranajit Bhattacharya. What is the difference between the respective rates of interest of the two banks?

Explanation:
Here we have Ranajit Bhattacharya.
P = ₹ 10000, time = 6 years 6 × 12 = 72 months and we have to find r%
Clearly,
MV = P × n + P ×\frac{(n)(n+1)}{2×12} × \frac{r}{100} \\ \text{(i) so that we get.} \\ 8,84,250 = ₹ 10000 × 72 + \frac{(72)(78)}{24} × \frac{r}{100}, \\ on solving we get: r% = 7.4%
Now for Lt Colonel Jayant:
P = ₹ 10000, time = 6 years 6 × 12 = 72 months and we have to find r% His maturity value is ₹ 19.710 less than the maturity value of Mr Ranajit:
I.e. ₹ 8,84,250 - ₹ 19.710 = ₹ 8,64,540 and rate is not known. Let it be R%
Clearly, ₹ 8,64,540
= ₹ 10,000 × 72 + = ₹ 10000 × \frac{(72)(78)}{24}×\frac{R}{100}, \\ on solving for R We get: R% = 6.6%
So the difference between the rate% = 7.4%- 6.6% = 0.8% Ans.

Frequently Asked Questions

Ans: Simple interest is calculated only on the initial principal amount, while compound interest takes into account both the principal and the accumulated interest.
Ans:  Simple Interest (SI) can be calculated using the formula: SI =\frac{P.R.T}{100}, \\ where P is the principal amount, R is the rate of interest, and T is the time in years.
Ans: The nominal interest rate is the stated interest rate, while the effective interest rate takes into account the compounding frequency. It is the actual rate at which interest is earned or paid.
Ans: The total amount (A) with annual compounding can be found using the formula: A= P(1 +\frac{R}{100})^T
Ans: Compound Interest (CI) is calculated using the formula: A= P(1 +\frac{R}{100})^T-P,\\ where A is the final amount, P is the principal, R is the rate of interest, and T is the time in years.
