1A principal sum of ₹10,000 is deposited in a commercial bank at a simple interest rate of 8% per annum for 3 years. What is the total interest earned and the final amount?
A.₹2,400 interest and ₹12,400 final amount
B.₹2,400 interest and ₹10,400 final amount
C.₹1,800 interest and ₹11,800 final amount
D.₹3,200 interest and ₹13,200 final amount
Explanation: Simple interest is calculated using SI = (P × R × T) / 100 = (10000 × 8 × 3) / 100 = ₹2,400. The final accumulated amount A = Principal + Interest = 10,000 + 2,400 = ₹12,400.
2Calculate the compound interest on a sum of ₹5,000 for 2 years at 10% per annum compounded annually.
A.₹1,000
B.₹1,050
C.₹1,100
D.₹6,050
Explanation: The compound amount formula is A = P(1 + r)^n = 5000(1 + 0.10)^2 = 5000(1.21) = ₹6,050. Compound interest CI = A - P = 6,050 - 5,000 = ₹1,050.
3A trader borrows ₹10,000 at 12% per annum compound interest, compounded half-yearly. What is the total interest payable at the end of 1 year?
A.₹1,200
B.₹1,236
C.₹1,248
D.₹11,236
Explanation: When compounded half-yearly, half-yearly rate r = 12% / 2 = 6% = 0.06, and conversion periods n = 2. Amount A = 10000(1 + 0.06)^2 = 10000(1.1236) = ₹11,236. Compound interest CI = 11,236 - 10,000 = ₹1,236.
4If money is invested at a nominal interest rate of 8% per annum compounded quarterly, what is the effective annual rate of interest?
A.8.00%
B.8.16%
C.8.24%
D.8.32%
Explanation: Effective annual rate r_eff = (1 + r/m)^m - 1 = (1 + 0.08/4)^4 - 1 = (1.02)^4 - 1 = 1.082432 - 1 = 0.082432 or 8.24%.
5A business firm purchases equipment for ₹50,000. If the estimated useful life is 5 years and residual scrap value is ₹5,000, calculate the annual depreciation using the Straight Line Method.
A.₹9,000
B.₹10,000
C.₹8,000
D.₹45,000
Explanation: Under the Straight Line Method, annual depreciation = (Cost - Scrap Value) / Life = (50,000 - 5,000) / 5 = 45,000 / 5 = ₹9,000 per year.
6A commercial motor vehicle costing ₹20,000 depreciates at 10% per annum on the Diminishing Balance Method (Reducing Balance). What is its written-down book value at the end of 2 years?
A.₹16,000
B.₹16,200
C.₹18,000
D.₹16,400
Explanation: Under the Diminishing Balance Method, book value after n years V_n = Cost × (1 - r)^n = 20000 × (1 - 0.10)^2 = 20000 × 0.81 = ₹16,200.
7A bill of exchange for ₹10,000 due 6 months hence is discounted by a bank at 6% per annum simple discount. What is the Banker's Discount (BD)?
A.₹300
B.₹291.26
C.₹600
D.₹9,700
Explanation: Banker's Discount BD = Face Value × Rate × Time = 10000 × 0.06 × (6/12) = 10000 × 0.06 × 0.5 = ₹300.
8The present value of a bill due 6 months hence is ₹5,000, and the total amount due at maturity is ₹5,300. Calculate the True Discount (TD) and the rate of simple interest per annum.
A.TD = ₹300, Rate = 12% p.a.
B.TD = ₹300, Rate = 6% p.a.
C.TD = ₹300, Rate = 10% p.a.
D.TD = ₹500, Rate = 12% p.a.
Explanation: True Discount TD = Amount - Present Value = 5,300 - 5,000 = ₹300. Rate R = (TD × 100) / (PV × T) = (300 × 100) / (5000 × 0.5) = 30000 / 2500 = 12% per annum.
9If the True Discount (TD) on a bill due 1 year hence at 10% per annum simple interest is ₹2,000, what is the Banker's Gain (BG)?
A.₹200
B.₹2,200
C.₹180
D.₹20
Explanation: Banker's Gain BG = BD - TD = Interest on TD for the unexpired time = (TD × R × T) / 100 = (2000 × 10 × 1) / 100 = ₹200.
10Find the Present Value of an ordinary annuity of ₹1,000 per annum payable for 3 years at an interest rate of 10% per annum compound interest.
A.₹2,487
B.₹3,000
C.₹3,310
D.₹2,727
Explanation: Present Value of ordinary annuity PV = R × [(1 - (1 + i)^(-n)) / i] = 1000 × [(1 - (1.10)^(-3)) / 0.10] = 1000 × [(1 - 0.751315) / 0.10] = 1000 × 2.48685 = ₹2,486.85 ≈ ₹2,487.

Assam HS Class 11-12 Business Mathematics & Statistics Study Tips from Top Performers

1Master financial formulas for compound interest A = P(1 + r/n)^(nt) and present value of ordinary annuity PV = R * [(1 - (1+i)^(-n)) / i].
2Practice matrix operations including finding cofactors, adjoints, inverse matrix A^(-1) = adj(A)/|A|, and solving linear equations via Cramer's Rule.
3Understand differential calculus business applications: compute marginal cost MC = dC/dx, marginal revenue MR = dR/dx, breakeven points where R(x) = C(x), and elasticity E_d = -(p/q)(dq/dp).
4Memorize formulas for standard deviation sigma = sqrt(sum(x - mean)^2 / N), coefficient of variation CV = (sigma / mean) * 100, and quartile deviation QD = (Q3 - Q1) / 2.
5Remember key properties of correlation and regression coefficients: r lies between -1 and +1, b_yx and b_xy have the same sign as r, and regression lines pass through the mean point (mean_x, mean_y).
6Learn index number formulas: Laspeyres uses base period quantities sum(p1*q0)/sum(p0*q0), Paasche uses current period quantities sum(p1*q1)/sum(p0*q1), and Fisher is sqrt(Laspeyres * Paasche).

Frequently Asked Questions

What topics are included in the Assam ASSEB HS Business Mathematics and Statistics syllabus?

The syllabus covers Commercial Arithmetic (interest, annuities, discounting, EMI), Matrices & Determinants, Differential Calculus (marginal cost/revenue, optimization, elasticity), Measures of Central Tendency & Dispersion, Karl Pearson & Spearman Correlation, Linear Regression, Index Numbers (Laspeyres, Paasche, Fisher), and Time Series Analysis.

What is the pass mark for ASSEB HS Business Mathematics and Statistics?

Students must secure at least 30% marks overall to pass the subject in the Higher Secondary Board Examination.

Why is Fisher's Index Number called the Ideal Index Number?

Fisher's Index Number is considered ideal because it is the geometric mean of Laspeyres and Paasche index numbers, uses both base year and current year weights, and satisfies both the Time Reversal Test and the Factor Reversal Test.

How are Marginal Cost and Marginal Revenue defined in Business Mathematics?

Marginal Cost (MC) is the instantaneous rate of change of total cost with respect to output, given by dC/dx. Marginal Revenue (MR) is the instantaneous rate of change of total revenue with respect to output, given by dR/dx. Profit is maximized when MR = MC and d^2(Profit)/dx^2 < 0.

What is the relationship between correlation coefficient and regression coefficients?

The correlation coefficient r is the geometric mean of the two regression coefficients b_yx and b_xy, given by r = +/- sqrt(b_yx * b_xy). Both regression coefficients and the correlation coefficient always share the same algebraic sign.

How does Cramer's Rule solve a system of linear equations using determinants?

Cramer's Rule calculates unknown variables by taking the ratio of column-substituted determinants to the main determinant D: x = D_x / D, y = D_y / D, and z = D_z / D, provided D is non-zero.
