Study the following table and answer questions:
Number of candidates appeared in an examination from five cities:
The number of candidates appearing for the examination from city D is what percent of the total number of candidates failed in cities A and B?
Solution
Total number of candidates failed in cities A and B (in thousands) = $$(\frac{2}{5}\times75)+(\frac{15}{31}\times124)$$
= $$30+60=90$$
Number of candidates appearing for the examination from city D = $$81$$
=> Required % = $$\frac{81}{90}\times100=90\%$$
=> Ans - (D)
