The total number of girls studied in MECH department from college Q and R together

= > 100*(32/100) + 80*(15/100)

= > 32 + 12 = 44

Required difference = 236 – 44 = 192

The total number of girls studied in EEE department from all the given colleges together

= > 220*(40/100) + 160*(50/100) + 180*(45/100) + 250*(54/100)
