Genaeral Folrmula for finding class mark =    Upper Limit + Lower Limit/2


Therefore, 
Class Mark for 10-25 =    25+10/2
                                   =     35/2
                                   =     17.5

Class Mark for 35-55 =   55+35/2
                                   =    90/2
                                   =    45



HOPE THIS WILL HELP YOU!!!!!!
THANKS!!!

We know that,
Upper limit + lower Limit /2 = Class mark
By using this formula ,
(Q.1) 10-25
 (Ans)-    10+25/2
         35/2 = 17.5

(Q.2)  35-55
(Ans)-   35+55/2 = 90/2
          =45

So the answer of your question is = 17.5 and 45 repectively....
