Answer.     [1263.15]
Solution.   n = 600
\frac{n}{2}= \frac{600}{2}= 300
l\iota= 1000, l = 1000, cf = 250, f = 190
median =  \iota +\left ( \frac{\frac{n}{2}-cf}{f} \right )\times h
= 1000+\frac{\left ( 300-250 \right )}{190}\times 1000
= 1000+\frac{50}{190}\times 1000
= 1000+\frac{5000}{19}
= \frac{19000+5000}{19}= \frac{24000}{19}= 1263\cdot 15
Median = 1263.15
