The following are the number of cases filed under Sec. 498A of Domestic Violence Act during the month of December, 2013, 2014 and 2015 at three cities, namely Pune, Hyderabad and Jaipur :

YearPuneHyderabadJaipur
2013405030
2014505550
2015506080

Which of the following statements are true ?

(i) Maximum increase occurred in Jaipur from 2014 to 2015.
(ii) Minimum increase occurred in Hyderabad from 2013 to 2014.
(iii) Average increase for the period together is lowest in the case of Hyderabad.
(iv) Minimum increase has occurred in the case of Pune from 2014 to 2015.

  • A.(i), (ii) and (iii)
  • B.(ii), (iii) and (iv)
  • C.(i), (iii) and (iv)
  • D.(i), (ii) and (iv)

Answer: D

The key gives (i), (ii) and (iv).

The year-on-year increases are:

City2013 to 20142014 to 2015
Pune100
Hyderabad55
Jaipur2030

(i) The largest increase in the table is Jaipur's 30, from 2014 to 2015: true. (ii) In the period 2013 to 2014, the smallest increase is Hyderabad's 5: true. (iv) In the period 2014 to 2015, the smallest increase is Pune's 0: true. Read period by period, as the key does, (ii) and (iv) each name the minimum for their own period.

(iii) is not true: the average increase over the two periods is 5 for Pune ((10 + 0)/2) and also 5 for Hyderabad, so Hyderabad is not uniquely the lowest. Every code that contains (iii) is therefore wrong.
