Answer»

1225
875
1050
700

Solution :We prepare following cumulative frequency table to find median CLASS.
We have `""N=100, (N)/(2)=50`
Cumulative frequency just greater than `(N)/(2)` is 60 and the CORRESPONDING class is 525-700. Thus median class is 525-700 and UPPER limit is 700.
Thus (d) is correct option.
