The answer must be B)4900 because 7268-2427 = (estimated form) 7300-2400=4900
Ans 5:
Class : Class 8
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

Class : Class 8
guys don't fight people just misunderstood the question also me I got it wrong i put 4800 as i did estimate first then subtract i guess all of us will learn from our mistakes
Ans 14:
Class : Class 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.

As there is a bracket, it means that we have to find the difference and then estimate the number.
Ans 18:
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

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