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 7

Ans 2:

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 3:

Class : Class 6
b is the correct answer

Ans 4:

Class : Class 6
ans is b

Ans 5:

Class : Class 10
the answer should be b

Ans 6:

Class : Class 10
its b

Ans 7:

Class : Class 6
correct answer is aaaaaaaaaaaaaaaaaaaaaaaaa

Ans 8:

Class : Class 9
THE CORRECT ANSWER IS A

Ans 9:

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 10:

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

Ans 11:

Class : Class 7
it should be C

Ans 12:

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 14:

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

Ans 15:

Class : Class 10
b is correct

Ans 16:

Class : Class 10
b is correct

Ans 17:

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 18:

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 19:

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 20:

Class : Class 7

Ans 21:

Class : Class 6
D is the correct answer

Ans 22:

Class : Class 7
a is correct

Ans 23:

Class : Class 6

Ans 24:

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 25:

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 26:

Class : Class 8

Ans 27:

Class : Class 8
1 is a factor of 6

Ans 28:

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 29:

Class : Class 6
the correct answer is c

Ans 30:

Class : Class 8
Answer is A

Ans 31:

Class : Class 10
sorry, a is the correct one

Ans 32:

Class : Class 9
the answer is b

Ans 33:

Class : Class 6
muuuuuuuuuuuuuuuuuusko munda

the angles are 80 degree and 100 degree. Method- 4:5=4x and 5x , 4x+5x=180 , 9x=180, x=180/9, x=20, therefore, 4:5= 4*20and 5*20 4:5=80 and 100

Very good Nilarka Pahari and Khushie. Friends , the correct answer is B only. Just try to see . Tilt your head to your right and try to see the cuts at the end of the ribbons . You will find the error of your own. Did you find that? I know that only 5 to 37 percent of you can nfind the eight angles. Be very accurate and intelligent. I also did the same mistake while giving the test . Please look carefully!

Ans 3:

Class : Class 6

Ans 4:

Class : Class 6
THE ANSWER IS 12 AS IF YOU LOKE AT ACUTE ANGLES IN THE EXTERIOR YOU CAN SEE 2 RIGHT ANGLES

Ans 5:

Class : Class 7
Thank you very much friends if you all co-operate me, Nilarka and Khushie!

Ans 6:

Class : Class 7
The answer is 4

Ans 7:

Class : Class 9

Ans 8:

Class : Class 6
answer is 4. how can it be 8

Ans 9:

Class : Class 6
On the outside, we see 4 right angles easily. But if you turn your device 90 degrees left/right, you will see that the angle formed by the sharp edges of the figure also measures 90 degrees. It is just not visible due to the angle you look at it.

Ans 10:

Class : Class 9
IT IS 8 ONLY

Ans 11:

Class : Class 8
answer is 4

Ans 12:

Class : Class 6

Ans 13:

Class : Class 7
It is Eight . If you tilt the small angles you will notice that there are eight right angles

Ans 14:

Class : Class 4
there cannot be 8

Ans 15:

Class : Class 4
It should be 4

Ans 16:

Class : Class 5
D.8

Ans 17:

Class : Class 6
No, it is 8. You can see 4 of them easily. The other four are hidden between the sharp edges of the figure. Tilt it 2 find out.

Ans 18:

Class : Class 6
The answer is D(8) because if we look at the V from a Tilted angle then it is a 90 degree angle. 4 V4 right angles4 4= 8

Ans 19:

Class : Class 4
Look closely. The answer is 8. If you look at the cuts in the ribbon which looks like a V at the top, you can see the right angle by tilting your device. Same follows with the other cuts

Ans 20:

Class : Class 7
The correct answer is 4. It cannot be 8 at all costs. There is a error!!!!!!!!!!

Ans 21:

Class : Class 5
B

Ans 22:

Class : Class 8
it cannot be 8 at all costs

Ans 23:

Class : Class 5
Look carefully, even I got to know the answer after reading the comments

Ans 24:

Class : Class 5

Ans 25:

Class : Class 6
IT IS 12

Ans 26:

Class : Class 7
The answer is 4 definitely!

Ans 27:

Class : Class 5
Everybody look carefully ! We use to be clever know we are not.

Ans 28:

Class : Class 5
THE ANSWER IS4

Ans 29:

Class : Class 8
How ??

Ans 30:

Class : Class 8
So report the error man

Ans 31:

Class : Class 7
It is 8

Ans 32:

Class : Class 8
4

Ans 33:

Class : Class 7
Actually it should be 4 or 12

Ans 34:

Class : Class 6

Ans 35:

Class : Class 4
No ,the answer is 8 because those small angles are also right angle

Ans 36:

Class : Class 8
It cannot be 8 at all costs There is an error in this question

Ans 37:

Class : Class 7
The answer is obviously 4.There cannot be 8 at all costs
