Study the given pie - charts and answer the question that follows.
The pie charts represent the percentage distribution of candidates qualified in a bank examination from six different districts of a State in 2016. The total number of qualified candidates from the State is 68000.
If 22% and 20% of the qualified students from Districts B and C, respectively, were 22 years old or below, then the number of qualified students who were above 22 years from District B is what percent (to the nearest integer) of the number of qualified students who were above 22 years from District C?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 87
The total number of qualified students from districts B = 68000 × 25/100 = 17000
The total number of qualified students from districts C = 68000 × 28/100 = 19040
Number of students from districts B above 22 years old = 17000 × 78/100 = 13260
Number of students from districts C above 22 yearls old = 19040 × 80/100 = 15232
Percent of the number of qualified students who were above 22 years from District C = 13260/15232 × 100 = 87.05%
