Ans 24:

Arihaan Adhikari from Modern Delhi International School, Sector 87, Faridabad

Ans 38:

Krishika Madan Shanmugam from National Public School, Bangalore
Class : Class 4
The answer should be A cause if number of students in science is 0 then adding values of math, english , hindi,and sanskrit should give 225, but its 190 so if we minus 190 from 225 the answer is 35. So number of people who like science is 35.If we add 35 with the number of people who like english that is 70, we get 105.SO THE ANSWER SHOULD BE A! NOT B, QUESTION IS WRONG!

total students are 225. but total of all subjects(leaving science) is 190. so the science student are 35. so number of student who are like science and english are 105.so answer a is correct.
