Ans 1:

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

Ans 2:

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

Ans 3:

Class : Class 6
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 4:

Class : Class 7

Ans 5:

Class : Class 6

Ans 6:

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

Ans 7:

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 8:

Class : Class 6

Ans 9:

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
