Direction (Q. 1 - 5) : Following pie-chart shows the monthly expenditure of a man on different items. His monthly income is Rs 20000.
How much (in Rs) does he spend on food items ?
26/100 x 20000 = 5200
What is the difference (in Rs) of the amount he spends on food and that on education ?
Food item = 5200
Education = 4000
∴ Diff = 1200
The ratio of the amount he spent on medical to that he spent for rent.

% increase in passed students from 1993 to 1994 was
320 - 180/180 x 100 = 77.77%
The average number of students passed from 1991 to 1995 was
160 + 200 + 180 + 320 + 275/5 = 1135/5 = 227
The average number of students admitted from 1991 to 1995 was
