estimate and then subtract

## Ans 3:

Class : Class 7
WHAT IS THE USE OF ESTIMATING IF WE ARE DOING THE NORMAL SUBTRACTION. THE ANSWER SHOULD BE 4900 AS THE NUMBER 7268 ESTIMATED TO THE NEAREST IS 7300 AND THEE NUMBER 2427 ESTIMATED TO THE NEAREST HUNDRED IS 2400. 7300-2400=4900

## Ans 4:

7268 - 2427 is in bracket . This means first to do subtraction and then estimate the answer to nearest hundreds ...........TRICKY question

## Ans 6:

Class : Class 4
it means first do subtraction and then estemate

## Ans 7:

Class : Class 6
it is simple 7268 - 2427 = 4841 rounded to the nearest hundreds = 4800

## Ans 8:

Class : Class 7
first we will do subtraction of 7268 and 2427 that is 4841 then we will estimate 4841 by nearest 100 which is 4800 and the anser is this first i have also done it according to NCERT but when result came then it was this solution

## Ans 9:

Class : Class 7
What is the point in estimating if we are anyway doing the actual subtraction? It makes sense if we round off the numbers 7268 and 2427 to the nearest hundred and then subtract, but that gives 7300-2400 viz.4900

## Ans 11:

Class : Class 6
it should be 4900 as we estimate first than subtract

## Ans 12:

Class : Class 6
because it is in bracket , we must subtract and then we must round off to nearest hundred

you are taking out average but if you tell you are a girl then you should know the answer

1:2 because lets take no. of boys as x then 70x will be total marks of boys lets take girls as y then 73y will be no of total marks of girls then 71x+71y will be equal to the total marks of whole class then we can say that 70x+73y=71x+71y it gives us x=2y so ratio will be 1:2
