State 'T' for true and 'F' for false and select the correct option.
(i) A prime number cannot have 0, 2, 4, 5, 6 and 8 at its ones place except 2.
(ii) Two numbers are called co-primes, if their L.C.M. is 1.

(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 7
your answer is wrong

Ans 2:

Class : Class 6
B is correct as 5 is a prime number in units place. Pls correct this Admin.

Ans 3:

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

Ans 4:

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 5:

Class : Class 8

Ans 6:

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

Ans 7:

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

Ans 8:

Class : Class 7
But 5 is prime

Ans 9:

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

Ans 10:

Class : Class 6
but 5 is primeso 1 is false

Ans 11:

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

Ans 12:

Class : Class 8
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 13:

Class : Class 7
5 is a prime number which makes the correct option as B

Ans 14:

Class : Class 7
So (i) is false.

Ans 15:

Class : Class 6

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 1:

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 2:

Class : Class 5

Ans 3:

Class : Class 4
A

Ans 4:

Class : Class 3
answer should be B not A

Ans 5:

Class : Class 5
but the given data is wrong and ans a not b

Ans 6:

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

Ans 7:

Class : Class 4
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 8:

Class : Class 6
answer should be B not A

Ans 9:

Class : Class 5

Ans 10:

Class : Class 4
A

Ans 11:

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

Ans 12:

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 13:

Class : Class 6

Ans 14:

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).

Ans 15:

Class : Class 5
answer should be A

Ans 16:

Class : Class 5
answer should be b not a

Ans 17:

Class : Class 4
the correct answer is B

Ans 18:

Class : Class 4

Ans 19:

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

Ans 20:

Class : Class 3

Ans 21:

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

Ans 22:

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

Ans 23:

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

Ans 24:

Class : Class 4
Answer should be B not A

Ans 25:

Class : Class 6
Answer should be A

Ans 26:

Class : Class 4

Ans 27:

Class : Class 4
A
