Class : Class 7
But 5 is prime

Ans 2:

Class : Class 6

Ans 3:

Class : Class 10

Ans 4:

Class : Class 7
it is B

Ans 5:

Class : Class 9
5 is a prime number which makes the correct option as B

Ans 6:

Class : Class 6
5 will be in units place so it has to be option B

Ans 7:

Class : Class 6
ans is b 5 is already a prime number

Ans 8:

Class : Class 6
5 itself is a prime number, so option i) cannot be true.The correct answer should be B.

Ans 9:

Class : Class 6
but 5 is primeso 1 is false

Ans 10:

Class : Class 6
ans. is wrong ,ans. is B

Ans 11:

Class : Class 6
5 is a prime number so the answer is wrong.

Ans 12:

Class : Class 6
option B is meant to be correct. 5 is prime number. people have sent these complaints 5 years ago. it is still not corrected.

Ans 13:

Class : Class 7
So (i) is false.

Ans 14:

Class : Class 7
To be more specific, the statement should have been: -A prime number cannot have 0,2,4,5,6 and 8 at its ones place except for 2 and 5.

Ans 15:

Class : Class 3
Ans is wrong. Opn B is correct.

Ans 16:

Class : Class 4
5 is prime so ( i ) is false but they have given that (i)is true why do they confuse us so much

Ans 17:

Class : Class 6
but 5 is prime so ( i ) is false but they have given that (i)is true

Ans 18:

Class : Class 7
your answer is wrong

Ans 19:

Class : Class 10
Its not possible to have a number divisible by 2 in case of the digit at ones place being 5. So, (i) is false.(ii)F(iii)T(iv)TSo, B should be the answer. But the answer says C. Have no ideas why.

Ans 20:

Class : Class 7
B is correct as 5 is a prime number in units place. Pls correct this Admin.

Answer should be B not A

Ans 2:

Class : Class 7
a

Ans 3:

Class : Class 6
Answer given is wrong, the correct answer is A.

Ans 4:

Class : Class 7
Answer should be A

Ans 5:

Class : Class 7
answer should be A

Ans 6:

Class : Class 10
answer should be B not A

Ans 7:

Class : Class 4
maybe its b because 35 students hate school and like no subjects

Ans 8:

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

Ans 9:

Class : Class 4
The correct answer is A not B

Ans 10:

Class : Class 4
Answer should be A

Ans 11:

Class : Class 6
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 12:

Class : Class 3
answer should be B not A

Ans 13:

Class : Class 4

Ans 14:

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

Ans 15:

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 16:

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 17:

Class : Class 5
Answer should be A not B.

Ans 18:

Class : Class 4
A

Ans 19:

Class : Class 4
The question is wrong. Someone please report error.

Ans 20:

Answer should be A not B

Ans 21:

Class : Class 8
Ans is a not b

Ans 22:

Class : Class 5

Ans 23:

Class : Class 4
ans is A

Ans 24:

Class : Class 5
the correct answer is B

Ans 25:

Class : Class 4
A

Ans 26:

Class : Class 4
thats true. we are more intelligent than them

Ans 27:

Class : Class 9
Yes it should be A as without science the number of students would be 190. Here the total number of students is 225

Ans 28:

Class : Class 4
is a not bi reported an error and is still showing b

Ans 29:

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 30:

Class : Class 5
A

Ans 31:

Class : Class 3
Answer must be A

Ans 32:

Class : Class 5

Ans 33:

Class : Class 4

Ans 34:

Class : Class 6
Yes the correct answer is A not B.

Ans 35:

Class : Class 4
Correct the answer from B to A pls

Ans 36:

Class : Class 6

Ans 37:

Class : Class 9
ANSWER IS A. Total number of students is 225. So science has to be 35. Its a glitch question!

Ans 38:

Class : Class 5
Ans should be A

Ans 39:

Class : Class 4
The answer is A not B.

Ans 40:

Class : Class 5
Yes, yes! The answer should be A or the question is wrong...

Ans 41:

Class : Class 8

Ans 42:

Class : Class 6
A

Ans 43:

Class : Class 5
The correct answer is A, not C. The answer is wrong

Ans 44:

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 45:

Class : Class 5
A IS ANS

Ans 46:

Class : Class 1
ANSWER SHOULD BE A OTHERWISE WRONG QUESTION NOT CONFUSE CHILD

Ans 47:

Class : Class 4
its not a direct question....

Ans 48:

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 49:

Class : Class 5
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!

Ans 50:

Class : Class 8

Ans 51:

Class : Class 4
The answer should be A. As per answer key, if Sci = 0, sum of all students will not be 225.

Ans 52:

Class : Class 5
answer should be b not a

Ans 53:

Class : Class 5
a is the answer because there are 225 students and without science it is only 190

Ans 54:

Class : Class 6
A

Ans 55:

Class : Class 4
ans is A

Ans 56:

Class : Class 5

Ans 57:

Class : Class 3
The Ans should be 'A' - 105 (225 - 190 = 35 Science and hence 70 (English) 35 (Science) = 105 )

Ans 58:

Class : Class 8

Ans 59:

Class : Class 7
Ans:AB is wrong

Ans 60:

Class : Class 6

Ans 61:

Class : Class 5
The answer should be A not B. Must be some mistake.

Ans 62:

Class : Class 4
A is the correct answer as without science there will be 190 students

Ans 63:

Class : Class 6
ans should be A not B

Ans 64:

Class : Class 5
Answer should be A because when we add every number it comes 190 and when we minus 190 from 225 it comes 35. when we add 35 and 70 it is 105 with proved with theory

Ans 65:

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 66:

Class : Class 8
but the given data is wrong and ans a not b

Ans 67:

Class : Class 5
Answer should be A or question is wrong
