The frequency distribution of the age of students in a class of $\displaystyle 40$ students is given below.
If the mean deviation about the median is $\displaystyle 1.25$ , then $\displaystyle 4 x+5 y$ is equal to :
| Age | $\displaystyle 15$ | $\displaystyle 16$ | $\displaystyle 17$ | $\displaystyle 18$ | $\displaystyle 19$ | $\displaystyle 20$ |
| No of Students | $\displaystyle 5$ | $\displaystyle 8$ | $\displaystyle 5$ | $\displaystyle 12$ | $\displaystyle x$ | $\displaystyle y$ |
