[A] 195 This is because it is written on the jar 200.This means that there cannot be more marbles than 200 in the jar.Options B,C and D have numbers more than 200,so the answer will be 195.

## Ans 2:

Class : Class 5
Since the jar is showing the rounded no 200 means it can hold 151 to 249 no of marbles. Question is to find how much it can hold means max how much it can hold. So it should be 240 as per the options given

## Ans 3:

Class : Class 5
Display of the question is wrong. They should have given 200 in the middle. If they have given it on the top it shows that only the leftover part of the jar is 200.

## Ans 4:

Class : Class 7
The correct answer is :- ' A 195' as we need to round off to the nearest hundred so when 195 is rounded off the answer is 200
