Option D. 96 is the correct answer.
Explanation:
Let the higher grade be = x
Let the lower grade be = y
As given, The difference of the two grades is 16
or
.... (1)
The sum of one-eighth of the higher grade and one-half of the lower grade is 52.
... (2)
Putting the value of x=16+y in equation (2)
![\frac{16+y}{8}+\frac{y}{2}=52](https://tex.z-dn.net/?f=%5Cfrac%7B16%2By%7D%7B8%7D%2B%5Cfrac%7By%7D%7B2%7D%3D52)
![\frac{16+y+4y}{8}=52](https://tex.z-dn.net/?f=%5Cfrac%7B16%2By%2B4y%7D%7B8%7D%3D52)
![\frac{16+5y}{8}=52](https://tex.z-dn.net/?f=%5Cfrac%7B16%2B5y%7D%7B8%7D%3D52)
![16+5y=416](https://tex.z-dn.net/?f=16%2B5y%3D416)
![5y=400](https://tex.z-dn.net/?f=5y%3D400)
![y=80](https://tex.z-dn.net/?f=y%3D80)
As x=16+y
x=16+80 = 96
Hence, higher grade is 96.
