Wow, I have never seen an I.R question like this where I had to consider unstated categories. Thank you Sajjad1994, for posting such an amazing question and helping me understand where I went wrong. Keep up the good work.

Sajjad1994, could you share the OE for this question, according to me the answer should be B(Former male smokers) and D(Remained Constant).

I would love to hear your take on this.

Official Explanation

Proportion of current female smokers went down by more than half which isn’t a 2nd choice. Proportion of former male smokers increased by maybe 1/4 which isn’t a 2nd choice. Females who never smoked would be an unstated 3rd category and in 1965 they would be ~58% of all women, then in 2015 they would have been about ~68% of all women which doesn’t match an answer choice. However, males who never smoked would be another unstated 3rd category and in 1965 they would have been approximately 28% of all men and in 2015 they would have been approximately 55% to match increased by more than half.

­Hi Aruneet,

Lets logically approach the question.

If we look at male smokers in 1965, it seems to be somewhere around 53% + males who left smoking were around 19%( all from the Chart)
Making men smokers(all) 72%. So we have 28% of men who never smoked.
Similarly, Now lets look the data from 2015, male smokers: 26% + males who left smoking were around 17% = 45% men smokers(all) , making the men who never smoked: 55%

Hope this helps!
