here l=50

n=90

cf=40+p

f=20

put the values in the formula you will find the value of p then put the value of p in p+q=12 you'll get the value of q also

aarchi82: why cf is 40+p

kumawatishika256: because the median class is 40-50 and we take c.f. that is just above that c.f. given in the middle class

kumawatishika256: median class

aarchi82: yaa how to take median class
