The pie-chart represents 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 68,000.
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?
The given pie charts show the distribution of students of graduate and postgraduate levels in five different institutes P, Q, R, S and T, in a town. Study the pie charts and answer the question that follows.
