Answer»

Solution :Using the GIVEN data, first of all, consturct a CUMULATIVE frequency table and then draw ogive (comulative frequency curve)
ltbr SINCE, the no. of terms n=35
`:. "Median"=((n+1)/(2))` th TERM
`=((35+1)/(2))` th term = 18 th term

Through mark 18 on Y-axis , draw a horizontal LINE which meets the curve at point A.
Through point A, on the curve, draw a vertical line which meets X-axis at point B. The value of point B on X-axis is median.
It is clear from the cumulative frequency curve drawn that the median is 26
