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 7

Ans 4:

Aayushi from Best English school, Ahmedabad
Class : Class 6

Ans 5:

Ans 8:

anjanikhairwar@gmail.com from S.V.K.M. J.V. PAREKH INTERNATIONAL SCHOOL, Mumbai
Class : Class 4
it means first do subtraction and then estemate

Ans 9:

Aryan Nangia from Sun city world school, Gurgaon
Class : Class 6

Ans 10:

Kanav Dhingra from DPS sec45, Gurgaon
Class : Class 6
if we apply BODMAS on this question, it says to solve the brackets first...

Ans 11:

Omkar Deshmukh from phoenix greens international school, Hyderabad
Class : Class 7
it should be 4900 as we estimate first than subtract

Ans 12:

ANUSHA from SATYA PRAKASH PUBLIC SCHOOL, Jabalpur
Class : Class 6
4900 should be the answer as we have to estimate first

Ans 13:

Archita from PSBB, Chennai
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:

Issac Newton from IIT Indian Institutes of Technology , Jalandhar
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:

DHEER PANDEY from Sentia School, Hyderabad
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:

Anagha s Karnis from vijaya vittala vidyashala, MYSORE
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:

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