JNU SSS 2013 Question 96: Quantitative aptitude and data reasoning

Answer Question Nos. 95–100 on the basis of the following information :

There are two experts, X1X_1X1​ and X2X_2X2​, employed by the Planning Commission of Hubble Bubble to calculate the annual rate of growth of output in the country. Given that Y(t)Y(t)Y(t) denotes output in year ttt and Y(t−1)Y(t-1)Y(t−1) denotes output in the previous year (t−1)(t-1)(t−1), X1X_1X1​ calculates the rate of growth in year ttt using the formula [Y(t)−Y(t−1)]/Y(t)[Y(t)-Y(t-1)]/Y(t)[Y(t)−Y(t−1)]/Y(t) and X2X_2X2​ calculates it using the formula [Y(t)−Y(t−1)]/Y(t−1)[Y(t)-Y(t-1)]/Y(t-1)[Y(t)−Y(t−1)]/Y(t−1).

Suppose Hubble Bubble’s output in 2012 was less than its output in 2011. Which expert calculated a higher rate of growth for 2012?

Answer Question Nos. 95–100 on the basis of the following information: There are two experts, X₁ and X₂, employed by the Planning Commission of Hubble Bubble to calculate the annual rate of growth of output in the country. Given that Y(t) denotes output in year t and Y(t-1) denotes output in the previous year (t-1), X₁ calculates the rate of growth in year t using the formula [Y(t)-Y(t-1)]/Y(t) and X₂ calculates it using the formula [Y(t)-Y(t-1)]/Y(t-1). Suppose Hubble Bubble’s output in 2012 was less than its output in 2011. Which expert calculated a higher rate of growth for 2012? (A) X₁ (B) X₂ (C) Both X₁ and X₂ calculated the same value for the rate of growth (D) Cannot be answered on the basis of the information provided

Also written as: Answer Question Nos. 95–100 on the basis of the following information: There are two experts, X_1 and X_2, employed by the Planning Commission of Hubble Bubble to calculate the annual rate of growth of output in the country. Given that Y(t) denotes output in year t and Y(t-1) denotes output in the previous year (t-1), X_1 calculates the rate of growth in year t using the formula [Y(t)-Y(t-1)]/Y(t) and X_2 calculates it using the formula [Y(t)-Y(t-1)]/Y(t-1). Suppose Hubble Bubble’s output in 2012 was less than its output in 2011. Which expert calculated a higher rate of growth for 2012?
