1.	How can we find classes if class mark & frequencies are given?Class mark - 325 & frequency - 25Class mark - 375 & frequency - 35
Answer» Answer: ⇒ Classmark= 2 Lowerlimit+Upperlimit ⇒ Given CLASS INTERVAL is 50−60 ⇒ Lower LIMIT =50 and upper limit =60 ∴ Classmark= 2 50+60 = 2 110 =55 ∴ The class mark of class onterval 50−60 is 55.
