A price rises from ₹80 to ₹100. What is the percentage increase?
Chapter 1: Ratio, Proportion and Percentage
Show answer
Answer: B. 25%
Increase = 20; percentage increase = 20/80 × 100 = 25% (always on the original value).What is the mean proportional between 4 and 9?
Chapter 1: Ratio, Proportion and Percentage
Show answer
Answer: A. 6
Mean proportional of a and b is √(ab) = √(4 × 9) = √36 = 6.At what rate of simple interest per annum will a sum of money double itself in 10 years?
Chapter 2: Simple and Compound Interest
Show answer
Answer: D. 10%
Doubling means SI = P, so P × R × 10/100 = P, giving R = 10%.In loan repayment, EMI stands for:
Chapter 3: Annuities and EMI
Show answer
Answer: B. Equated Monthly Instalment
An EMI is a fixed amount paid every month that covers both interest and part of the principal.If matrix A is of order 2 × 3 and matrix B is of order 3 × 4, what is the order of the product AB?
Chapter 4: Matrices and Determinants
Show answer
Answer: C. 2 × 4
AB exists because columns of A (3) = rows of B (3); the product has the rows of A and the columns of B: 2 × 4.In a pie diagram, what angle represents an item that is 25% of the total?
Chapter 5: Collection, Classification and Presentation of Data
Show answer
Answer: D. 90°
The whole circle (360°) stands for 100%, so 25% gets 25/100 × 360° = 90°.What is the median of the values 3, 8, 5, 12 and 10?
Chapter 6: Measures of Central Tendency
Show answer
Answer: C. 8
Arranged in order: 3, 5, 8, 10, 12; the middle (3rd) value is 8. (7.6 is the mean, not the median.)Using the empirical relation Mode = 3 Median − 2 Mean, find the mode when the mean is 40 and the median is 38.
Chapter 6: Measures of Central Tendency
Show answer
Answer: A. 34
Mode = 3 × 38 − 2 × 40 = 114 − 80 = 34.If the first quartile Q₁ = 20 and the third quartile Q₃ = 40, what is the quartile deviation?
Chapter 7: Measures of Dispersion
Show answer
Answer: B. 10
Quartile deviation = (Q₃ − Q₁)/2 = (40 − 20)/2 = 10.The two regression coefficients are byx = 0.8 and bxy = 0.45. What is the coefficient of correlation r?
Chapter 8: Correlation and Regression
Show answer
Answer: C. 0.6
r = √(byx × bxy) = √(0.8 × 0.45) = √0.36 = 0.6, positive because both coefficients are positive.
