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 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 7:

Class : Class 7
it should be 4900 as we estimate first than subtract

## Ans 8:

Class : Class 6
4900 should be the answer as we have to estimate first

## Ans 9:

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

## Ans 10:

It generally mentioned clearly what to do first, the actual subtraction or the estimation by SOF. But here, they asked us to estimate 7268-2427. So,we should first do the actual subtraction. By that the answer is 4800.

## Ans 11:

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

## Ans 12:

Class : Class 6
estimate and then subtract

## Ans 13:

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

## Ans 15:

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 16:

Class : Class 6
if we apply BODMAS on this question, it says to solve the brackets first...

## Ans 17:

Class : Class 8
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

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
