State 'T' for true and 'F' for false and select the correct option.

(ii) Two numbers are called co-primes, if their L.C.M. is 1.
(iii) If X is a factor of Y and Y is a factor of Z, then X is also a factor of Z.
(iv) 4 is the smallest composite number.

A
B
C
D


I think correct answer is B. Because all the numbers having 2 at ones are not prime number

Ans 1:

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 2:

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

Ans 3:

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

Ans 4:

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

Ans 5:

Class : Class 6
but 5 is primeso 1 is false

Ans 6:

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

Ans 7:

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

Ans 10:

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 11:

Class : Class 7
So (i) is false.

Ans 12:

Class : Class 7
your answer is wrong

Ans 13:

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

Ans 14:

Class : Class 10

Ans 15:

Class : Class 6

Ans 16:

Class : Class 7
But 5 is prime

Ans 17:

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

Ans 13:

A

Ans 16:

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

Ans 17:

Class : Class 4
Answer should be B not A

Ans 18:

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 19:

Class : Class 7
No! The answer is A. 60 70 20 40 = 190 which is NOT 225.Science = 35, English = 70 so answer is 105(A).

Ans 20:

Class : Class 4
Yes, yes! The answer should be A or the question is wrong...

Ans 21:

Class : Class 3
answer should be B not A

Ans 22:

Class : Class 4
A

Ans 23:

Class : Class 4
ANSWER IS A. Total number of students is 225. So science has to be 35. Its a glitch question!

Ans 24:

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

Ans 25:

Class : Class 4
ans should be A not B

Ans 26:

Class : Class 7

Ans 27:

Class : Class 4

Ans 28:

Ans 31:

Class : Class 4
Answer given is wrong, the correct answer is A.

Ans 32:

Class : Class 4
Yes the correct answer is A not B.

Ans 33:

Class : Class 7
Yes it should be A as without science the number of students would be 190. Here the total number of students is 225

Ans 34:

Class : Class 4

Ans 35:

Class : Class 6

Ans 36:

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 37:

Class : Class 6
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 38:

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 39:

Class : Class 4
The answer is A not B.

Ans 40:

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