zoloto Posted July 30, 2015 Report Posted July 30, 2015 Total no of students is equeal to n.. n value sona cheptadu :police: n value is 500. lets say chemistry students only as x phy students only as y bio students only as z chem and phy only = 97-73 = 24 chem and bio only = 152-73 = 79 phy and bio = 138-73 = 65 now x = 280-24+73+79 = 104 y = 254-24+73+65 = 92 z= 280-79+73+65 = 63 total number of students = chem only + bio only + phy only + chem and Bio only + chem and phy only + phy and bio only + chem, bio, phy only
