A 100
B
C 10
D 1000


stupid answer it is actually c

Ans 1:

Class : Class 8
ans. should be [C].

Ans 2:

Class : Class 6
The correct answer is C as 100/10 is 10, 1000/100 is also 10.

Ans 3:

Class : Class 8
c is right because we have to multiply cause we are given times.. 1000x___= 100... so we get 1000/10= 10 so c is right

Ans 4:

Class : Class 9
The answer is B cause they are saying step by step from LEFT to RIGHT that means it is increasing but as they have said decreasing the answer is B . eg- 10 increases by 10 when it goes from tens to hundred. So it decreases by this formula - 10 divided by 1/10 ( dividing a whole number by a fraction = whole number X the reciprocal of the fraction) = 10x10 = 100

Ans 5:

Class : Class 7
Answer should be C

Ans 6:

Class : Class 6
answer should be C because it already says the word divide and if we write ans as B then it will become ( eg. 100/1/10 = 1000) hence it should be ( eg. 100/10 = 10) . PLS CORRECT IT SOF !!!!!

As he is saying times, it should be 10 and not 1/10. So, answer should be C

Ans 11:

Class : Class 7
ans should be cccc.

Ans 12:

Class : Class 7
Answer should be C

Ans 13:

Class : Class 10
answer is bwhen we move from left to rightexample-1000 to 100how do you get 100 by dividing it by 10 right?i.e 1000/10 = 100answer = 1/10

Ans 14:

Class : Class 10
answer should be c

Ans 15:

Class : Class 9
in synopsis its given that the place value decreases by 10

Ans 16:

Class : Class 9
and should be c

Ans 17:

Ans is C, the most sigma

Ans 18:

Class : Class 10

Ans 21:

Class : Class 9
THE ANSWER IS - B

Ans 22:

Class : Class 8
it should be B as it is decreased by not increased if it was increased than it was 10

Ans 23:

Class : Class 7
the answer is C.. B is the wrong answer . if we have to move the digits from left to right we should multiply and not divide.. please clarify SOF..

Ans 24:

Class : Class 8
answer should be c not b

Ans 25:

Class : Class 8
C

Ans 26:

Class : Class 7

Ans 30:

Class : Class 6
Ans c only makes sense

Ans 31:

Class : Class 8
Decreases means division and increases means multiplication.Over here it says decreases and therefore it is division.For example let us take 100.(B) 100/ 1/10 = 100 * 10 = 1000(C)100/10 = 10Therefore,C is correct as 1 moves from left to right.

Ans 32:

Class : Class 6
The and should be C

c

Ans 36:

Class : Class 6
The CORRECT answer is CCCCCCCCCCC mr SOF

Class : Class 10

Ans 38:

Class : Class 6
My explaination is when we decrease a number by 1/10 times example 100 / 1/10 = 1000 so it increases by 10. If in place of decrease it was increase then b would be the answer but actual answer is c.

Ans 39:

Class : Class 6
how can it decrease by 1/10. it changes by 1/10 and decreases by 10 times answer should be C

Ans 40:

Class : Class 9
I think answer is B.....as we have to divide the digit by number 10 each time we move from left to right .....and so its value decreases eg 500 is divided by 10 (500*1/10 = 50) to make its place value from hundred to tens

Ans 41:

Class : Class 10
c

Ans 42:

Class : Class 9
THE ANSWER SHOULD BE (B) PLEASE VERIFY SOF!!!!

Ans 43:

Class : Class 6
c

Ans 44:

Class : Class 5
correct ans. should be C

Ans 45:

Class : Class 6
The answer is c. It decreases by 1 by 10 when it goes from right to left, not from left to right.

Ans 46:

Class : Class 8
correct ans. should be C

Ans 47:

Class : Class 6
Ans should be (c)

Ans 48:

Class : Class 7
Remember LEFT TO RIGHT

Ans 49:

Class : Class 10
The answer is (c)

Ans 50:

Class : Class 7
decreasing by 1/10 is not possible . the answer should be (c)

Ans 51:

Class : Class 7
ans should be C

Ans 52:

Class : Class 9
Its C

Ans 53:

Class : Class 8
The correct answer is (C) because the question asks you by how many times it is DECREASING from LEFT TO RIGHT . If it said increasing, then the answer would be (B)

Ans 54:

Class : Class 6
the correct answer is [B] because if we take a no. as 10.ok.then i am doing like example see- 10X1/10 so it is =1 so it decreased
