add solution to this question

Ans 1:

Class : Class 9
the answer is b

Ans 2:

Class : Class 6
statement 1- The definition of perfect number on google is the same as the definition of perfect number provided by the question as for statement 2 eg 6 and 4 is divisible by 2 so 6 4= 10 div by 2 and 6-4= 2 also div by 2. so people who say answer is b c or d are complete idiots

Ans 3:

Class : Class 6
ans is b

Ans 4:

Class : Class 8
I am confused what is the answer because some are saying a , some are saying b ,some are saying c and some are saying d .

Ans 5:

Class : Class 9
According to me ,it is C

Ans 6:

Class : Class 8
according to me , its B as if two numbers are divisible by a number , their sum and difference is not divisible by the same number . For example : 2

Ans 7:

Class : Class 6
it should be A because if we take 39 and 26 as multiples and 13 as factor then 39-26=13. which is divisible by 13

Ans 8:

Class : Class 7

Class : Class 6
muuuuuuuuuuuuuuuuuusko munda

Ans 10:

Class : Class 10
b is correct

Ans 11:

Class : Class 10
b is correct

Ans 12:

Class : Class 6
some are saying a, some are saying b, some are saying c and some are saying d. what is the correct answer??????

Ans 13:

Class : Class 9
THE CORRECT ANSWER IS A

Ans 17:

Class : Class 8
Answer is A

Ans 18:

Class : Class 7
a because lets take 6, its factors are 1,2,3,6. When we add these numbers we get 12 which is twice 6

Ans 19:

Class : Class 6
b is the correct answer

Ans 20:

Class : Class 6
THE ANSWER SHOULD BE NONE OTHER THAN C. NOT A , NOT B OR NOR D. NOOOOOO ABD

Ans 21:

Class : Class 6

Ans 22:

Class : Class 10
its b

Ans 23:

Class : Class 6
D is the correct answer

Ans 24:

Class : Class 7
it should be C

Ans 25:

Class : Class 10
sorry, a is the correct one

Ans 26:

Class : Class 7
a is correct

Ans 27:

Class : Class 7
The answer can only be C. For the first statement, If you take an example as 6, it will be 1 2 3=6 which means statement 1 is false as it is written that it should be double. Statement 2 is true. For example, take 25 and 20 and the number as 5. 25 20=45(Divisible by 5) and 25-20=5(Divisible by 5)

Ans 28:

Class : Class 7
The ans is a becauseStatement 1: if we take the number 6 its factors except 6 are 1,2,3 there sum is 6 so it is a perfect numberStatement 2: If we take 9 and 27 they are divisible by 3 so their sum which is 36 is also divisible by 3 and there diffrence is 18 which is divisible by 3.

Ans 29:

Class : Class 7

Ans 30:

Class : Class 6
its b because say if you take 6,and you say 2 and 3 are divisible by it. then they are saying that their sum and diff is also divisible but 2 3 is 5 which is not divisible by 6

Ans 31:

Class : Class 8
1 is a factor of 6

Ans 32:

Class : Class 7
According to me, A is the correct answer.

Ans 33:

Class : Class 10
the answer should be b

Ans 34:

Class : Class 6
correct answer is aaaaaaaaaaaaaaaaaaaaaaaaa

Ans 35:

Class : Class 8
