SUBTRACT AND THE ESTIMATE !!!

## Ans 3:

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

Class : Class 7

## Ans 5:

Class : Class 7
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 6
4900 should be the answer as we have to estimate first

## Ans 7:

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

## Ans 9:

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

## Ans 11:

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 12:

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

## Ans 13:

Class : Class 6
estimate and then subtract

## Ans 14:

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 15:

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

## Ans 16:

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

## Ans 17:

Class : Class 7
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.

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
