Subject :IMO Class : Class 6
Read the following statements.
Statement-1 :A number for which sum of all its factors is equal to twice the number is called perfect number.
Statement-2 :If two numbers are divisible by a number, then their sum and difference are also divisible by that number.
Which of the following options holds?
A Both Statement-1 and Statement-2 are true.
B Statement-1 is true but Statement-2 is false.
C Statement-1 is false but Statement-2 is true.
D Both Statement-1 and Statement-2 are false.
add solution to this question
Ans 1:
Class : Class 10
b is correct
Ans 2:
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 3:
Class : Class 10
the answer should be b
Ans 4:
Class : Class 6
ans is b
Ans 5:
Class : Class 8
1 is a factor of 6
Ans 6:
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 7:
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 8:
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 9:
Class : Class 9
THE CORRECT ANSWER IS A
Ans 10:
Class : Class 6
the correct answer is c
Ans 11:
Class : Class 9
According to me ,it is C
Ans 12:
Class : Class 6
THE ANSWER SHOULD BE NONE OTHER THAN C. NOT A , NOT B OR NOR D. NOOOOOO ABD
Ans 13:
Class : Class 10
its b
Ans 14:
Class : Class 8
Answer is A
Ans 15:
Class : Class 8
Ans 16:
Class : Class 7
a is correct
Ans 17:
Class : Class 6
muuuuuuuuuuuuuuuuuusko munda
Ans 18:
Class : Class 10
sorry, a is the correct one
Ans 19:
Class : Class 6
b is the correct answer
Ans 20:
Class : Class 7
According to me, A is the correct answer.
Ans 21:
Class : Class 7
b
Ans 22:
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 23:
Class : Class 6
Ans 24:
Class : Class 6
correct answer is aaaaaaaaaaaaaaaaaaaaaaaaa
Ans 25:
Class : Class 6
D is the correct answer
Ans 26:
Class : Class 9
the answer is b
Ans 27:
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 28:
Class : Class 7
it should be C
Ans 29:
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 30:
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 31:
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 32:
Class : Class 7
Ans 33:
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 34:
Class : Class 7
Ans 35:
Class : Class 10
b is correct
