Sample WBCHSE HS Business Mathematics and Basic Statistics Practice Questions

Try these sample questions to test your WBCHSE HS Business Mathematics and Basic Statistics exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 90+ question experience with AI tutoring.

1What is the simple interest on INR 3619 for 1 years at 3% per annum?
A.208
B.216
C.108
D.58
Explanation: Simple Interest = (P * R * T) / 100 = (3619 * 3 * 1) / 100 = 108.57.
2Find the arithmetic mean of the following data points: 18, 16, 44, 15, 47.
A.30.0
B.27.0
C.28.0
D.33.0
Explanation: Mean = Sum of observations / Number of observations = 140 / 5 = 28.0.
3If the base year price is INR 111 and the current year price is INR 205, what is the price index number (Price Relative) for the current year?
A.92.34
B.184.68
C.202.97
D.169.42
Explanation: Price Index = (Current Price / Base Price) * 100 = (205 / 111) * 100 = 184.68.
4Calculate the compound interest on INR 2794 for 3 years at 9% per annum compounded annually.
A.924.31
B.774.31
C.754.38
D.824.31
Explanation: Amount = P(1 + R/100)^T = 2794(1 + 9/100)^3 = 3618.31. Compound Interest = Amount - P = 824.31.
5The total cost function is given by C(x) = 132 + 15x + x^2, where x is the quantity produced. Find the marginal cost when 11 units are produced.
A.26
B.37
C.32
D.47
Explanation: Marginal Cost (MC) is the derivative of the total cost function with respect to x. MC = dC/dx = 15 + 2x. At x = 11, MC = 15 + 2(11) = 37.
6Find the present value of an ordinary annuity of INR 107 per annum for 6 years at 4% p.a. compound interest.
A.642.00
B.504.82
C.560.91
D.617.00
Explanation: Present Value (PV) = R * [(1 - (1+i)^-n) / i]. Here R = 107, i = 4/100 = 0.04, n = 6. PV = 107 * [(1 - (1+0.04)^-6) / 0.04] = 560.91.
7Evaluate the determinant of the matrix A = [[5, 5], [3, 4]].
A.-5
B.5
C.7
D.0
Explanation: Determinant = (a11 * a22) - (a12 * a21) = (5 * 4) - (5 * 3) = 20 - 15 = 5.
8Calculate the standard deviation for the sample data points (treated as population for formula): 26, 25, 15, 12.
A.6.10
B.37.25
C.5.10
D.8.10
Explanation: Mean = 19.5. Variance = Sum((x - mean)^2) / N = 37.25. Standard Deviation = sqrt(Variance) = 6.10.
9Simple interest on INR 2000 at 8% p.a. for 3 years is:
A.INR 480
B.INR 160
C.INR 2000
D.INR 240
Explanation: SI=2000*8*3/100=480.
10Amount on INR 1000 at 10% CI for 2 years (annual) is:
A.INR 1210
B.INR 1200
C.INR 1100
D.INR 1000
Explanation: Compound growth gives 1000 × 1.1² = 1210.
