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 3:

Class : Class 7

Ans 4:

Class : Class 6

Ans 5:

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

Ans 6:

Class : Class 6
SUBTRACT AND THE ESTIMATE !!!

Ans 7:

Class : Class 6
estimate and then subtract

Ans 8:

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

Ans 9:

Class : Class 6

Ans 10:

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

Ans 11:

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

Ans 12:

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

Ans 13:

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 14:

Class : Class 5
7268 - 2427 is in bracket . This means first to do subtraction and then estimate the answer to nearest hundreds ...........TRICKY question

Ans 15:

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.

Ans 16:

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 17:

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