Ans 2:

Oscar Maltman from DBSEH, dubai
Class : Class 10
sorry i meant 4900

Ans 3:

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

Ans 4:

Pranit Sinha from Montfort School, Roorkee, Haridwar
Class : Class 6
SUBTRACT AND THE ESTIMATE !!!

Ans 5:

Anusha from LBS School , Kota
Class : Class 10

Ans 8:

VYOM VIVEK PATEL from Doon Public School Bhuj, Bhuj Kuchchh
Class : Class 9
The answer must be B)4900 because 7268-2427 = (estimated form) 7300-2400=4900

Ans 9:

Shreyansh Gupta from MVN, faridabad
Class : Class 7
stop fighting

Ans 10:

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

Ans 11:

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 12:

Shreyansh Gupta from MVN, faridabad
Class : Class 7
THERE IS NO ANSWER 4900,4800 BLAH BLAH BRUH !!!!!!!

Ans 13:

ankit from i like peeing, i hate my self

DEVAANGANA SARDAR from G.D. Birla Centre for Education, Kolkata
Class : Class 7
Seriously

Ans 15:

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.

Ans 16:

Miraya Agarwal from School of india, Bengaluru
Class : Class 6
Answer is A because when you divide 163/14 you get 11. 11 rounded of to the nearest tens is 10

Ans 17:

Kavya Gupta from Spring Dale School, Amritsar
Class : Class 7

Ans 18:

VEERANGANA SINGH from DPS NOIDA, NOIDA
Class : Class 7
THE ANSWER IS A NOT B

Ans 19:

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

Ans 20:

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 21:

malhar thorve from city internqtional school, satara road, pune
Class : Class 7
they told us to round the quotient to nearest tens so the answer is not 16 the answer is 10

Aayushi from Best English school, Ahmedabad
