34 is 6 greater than 28 so two small arcs wont add up to that amount

Ans 2:

Class : Class 6
if its less then 1/2 then it should be 0...the ANSWER IS A

Ans 3:

Class : Class 6
28 should be the answer then

I agree with Mukil

Another mistake by SOF. Two mistakes in one exam! Correct option is A because if we take 1 square as 1 sq. cm, then two less than half arcs won't add up to 6 but rounded off to 0. My marks should be 55, not 53

Ans 9:

Class : Class 7
please check the answer.it should be 28 sq.cm
