Answer

S.No.CausesFemale fatality rate (%)
1Reproductive health condition (RHC)31.8
2Neuropsychiatric conditions (NC)25.4
3Injuries (I)12.4
4Cardiovascular conditions (CC)4.3
5Respiratory conditions (RC)4.1
6Other causes (OC)22.0

(i) Steps of construction :

  1. Plot the causes on x-axis.

  2. Plot female fatality rate on y-axis by taking 1 cm = 4%.

  3. To represent our first Head, i.e., (RHC), we draw a rectangular bar with width 1 unit and height 31.8 units.

  4. Similarly, other Heads are represented leaving a gap of 1 unit in between two consecutive bars.
