Santosh Kumar Gupta from Elpro International School, Chinchwad, Pune
Class : Class 4
Answer should be A

Ans 4:

Kaarthikeya Sharma N from Shantiniketan International School, Secunderabad
Class : Class 5
Answer should be A. If Science is not taken by any student, then which subject is taken by remaining 35 students?

Ans 5:

Shyam Jayesh from Gopalan International School, Bangalore
Class : Class 3
Total students liking the subjects are 225. Maths-60, English-70, Hindi-20, Sanskrit-40. Remaining 35 students must be liking science. Hence answer must be A.

Ans 6:

Siddharth Laxmisha from The Study Lecole Internationale, PUDUCHERRY
Class : Class 8
No! The answer is A. 60 70 20 40 = 190 which is NOT 225.Science = 35, English = 70 so answer is 105(A).

Ans 7:

Aayush from podar interntional, Jalna
Class : Class 4
ans is A

Ans 8:

ISHAAN ROY from NPS SINGAPORE, Singapore
Class : Class 9

Ans 15:

Ahaan Mittal from Primus Public School, Bengaluru
Class : Class 8

Ans 16:

Daiwik Sunil from RAJAGIRI PUBLIC SCHOOL, Doha
Class : Class 8
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 17:

gauri gupta from st. paul's church college, Agra, AGRA
Class : Class 3
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.

Ans 18:

Ans 24:

Parth Katyal from DPS Gurgaon, Gurgaon
Class : Class 6

Ans 25:

Aryan from Sai international, Bhubaneswar
Class : Class 9
The question is wrong because the total is 225 students and to find number of students who like science we will subtract the total of maths,english ,hindi and sanskrit with 225 and add the answer to students who like english .So the answer came as 100

Ans 26:

Aarohi from Bhavans Rajaji Vidyashram, Chennai
Class : Class 5

Ans 27:

AARUSH JAIN from DPS NOIDA, DELHI

Class : Class 4
'b' is so wrong it should be 'a' because total students - 225students in all subjects except for science - 60 40 70 20 = 190no. of students in science - 35so 35 70 = 105

Ans 31:

Aaratrika Sinha from Vels Global School , Kolkata
Class : Class 5
Answer should be A

Ans 32:

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!

A

Ans 42:

Ans 43:

Atharv Rai from The Foundation School , Bangalore
Class : Class 4
if it is b than total students should be 190but since it is 225 you add it and you 'll get 190when you subtract both the numbers you will get 35since English is 70 you add the 70 to 35 and you will get 105 so a is the ans
