The solution we get by subtracting the lower limit of 2nd class interval and upper limit of 1st class should added to upper limits of all classes and subtracted from lower limit of all classes for example 17-19 20-22 23-25 26-28 is given we make it continuous in this way 20-19/2=0.5 therefore the classes are 16.5-19.5 19.5-22.5 22.5-25.5 25.5-28.5
for example let the classes are 20-29 30-39 40-49 u can change it as 19.5 - 29.5 here lower limits are subtracted 0.5 upper limits added 0.5 29.5 - 39.5 39.5 - 49.5

17-19
20-22
23-25
26-28
is given we make it continuous in this way 20-19/2=0.5
therefore the classes are 16.5-19.5
19.5-22.5
22.5-25.5
25.5-28.5
hope it helps...

19.5 - 29.5 here lower limits are subtracted 0.5 upper limits added 0.5
29.5 - 39.5
