Ans 8:

Dheer Pandey from Sentia The Global School, Hyderabad
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.

Ishitadas from Adamas World school , Ichapur

Shreyansh Gupta from MVN, faridabad

Ans 12:

Hanan Fathima Shabeer from ,
Class : Class 6

Ans 13:

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 14:

Aryan Mahanty from Delhi Public School, bangalore
Class : Class 6
it is simple 7268 - 2427 = 4841 rounded to the nearest hundreds = 4800

Ans 15:

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 16:

Krithi Manasvini from Alwin Memorial Public School, Chennai
Class : Class 7
We have 7268 – 2427 = 4841 Rounded off 4841 to nearest hundred = 4800

Ans 17:

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
