Solution

The correct option is D None of these
The data given in the graph can be tabulated as given below:
$\begin{matrix} C o l l e g e & 1988 - 89 & 1989 - 90 & 1990 - 91 P r i v a t e E n g g . C o l l e g e & 120 & 180 & 250 G o v t . E n g g . C o l l e g e & 80 & 120 & 130 R e g i o n a l E n g g . C o l l e g e & 40 & 75 & 100 I I T & 30 & 40 & 80 \end{matrix}$
Total number of students in 1990-91 = (250 + 130 + 100 + 80) 100 = 56000.
Hence the total number of students in 1991-92 = 0.9 $\times$ 56000 = 50400.
