Explanation / Answer

Hi,

The composition of 300 young women split by geographical area is 169,104 & 27 for urban, semiurban and rural respectively. You have selected the right pie chart(B) because the area covered by each geographical area correctly captures the split.

Now, you are supposed to calculate the percentage of each geographical area. The thumb rule to create percentages is first calculate probability and them mutliply it by factor. Here, probability is (Favourable outcomes)/(No. of outcomes).

For urban, probability will be no. of women from urban area/total women = 169/300=0.5633 and the corresponding percentage is 0.5633*100=56.3%.

Similarly for semiurban required percentage is (104/300)*100=34.7% and for rural is (24/300)*100=8%.
