Subject :IMO    Class : Class 6

Place value of a digit decreases by ______ times as it moves place by place from left to right.

A 100
B
C 10
D 1000


stupid answer it is actually c

Ans 1:

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 2:

Class : Class 8
answer should be c not b

Ans 3:

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

Ans 4:

Class : Class 7
Remember LEFT TO RIGHT

Ans 5:

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

Ans 6:

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 7:

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

Ans 8:

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 9:

Class : Class 10

Ans 10:

Class : Class 6
the answer should be option C

Ans 11:

Class : Class 7
Cccc!

Ans 13:

Class : Class 10
The answer is (c)

Ans 14:

Class : Class 9
Its C

Ans 15:

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 16:

Class : Class 5
correct ans. should be C

Ans 17:

Class : Class 7
c

Ans 18:

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

Ans 19:

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

Class : Class 7
ans should be c

Ans 21:

Class : Class 7
ans should be cccc.

Ans 22:

Class : Class 6
The and should be C

Ans 23:

Class : Class 7
answer should be Cas 100 /10 is 10

Ans 24:

Class : Class 9
and should be c

Ans 25:

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 26:

Class : Class 6
Ans is (c).

Ans 27:

Class : Class 8
C

Ans 28:

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 29:

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 30:

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 !!!!!

Ans 31:

Class : Class 7
look at solution please

Ans 32:

Class : Class 6
Ans is C, the most sigma

Ans 33:

Class : Class 8

Ans 34:

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

Ans 35:

Class : Class 8
correct ans. should be C

Ans 36:

Class : Class 9
As he is saying times, it should be 10 and not 1/10. So, answer should be C

Ans 37:

Class : Class 7
c

Ans 38:

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

Ans 39:

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

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
