Ans 1:

Class : Class 4
the correct answer is B

Ans 2:

Class : Class 5
Yes it should be A as without science the number of students would be 190. Here the total number of students is 225

Ans 3:

Class : Class 4
The answer should be A. There is no value had given for science. Without that the total is 190. If we calculate the marks scored science out of 225, then the mark in science has to be 35. Hence the total has to 105, which is answer A

Ans 4:

Class : Class 5
There is no figure given for science student thus the answer is B.

Ans 5:

Class : Class 4
No! The answer is A. 60 70 20 40 = 190 which is NOT 225.Science = 35, English = 70 so answer is 105(A).
