a = 15
b = 20
c = 47
d = 3
e = 5
f = 60
g = 60
all values can be found by comparing each value of frequency with corresponding cumulative frequency
b = 20
c = 47
d = 3
e = 5
f = 60
g = 60

rohanharolikar:
c + d = 50 so d is 50-47 = 3
thank you
50 is sum of all frequencies up to d and 55 is sum of all frequencies up to e
so e is 55 - 50 = 5
f is 55 + 5 = 60
g is sum of all frequencies thus it is 60
did you understand well
thanks
