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

7268 - 2427 is in bracket . This means first to do subtraction and then estimate the answer to nearest hundreds ...........TRICKY question
Ans 12:
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 15:
Class : Class 8
As there is a bracket, it means that we have to find the difference and then estimate the number.
Ans 19:
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
Ans 20:
Class : Class 8
The answer must be B)4900 because 7268-2427 = (estimated form) 7300-2400=4900
Ans 21:
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 24:
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

1:2
because
lets take no. of boys as x then 70x will be total marks of boys
lets take girls as y then 73y will be no of total marks of girls
then 71x+71y will be equal to the total marks of whole class
then we can say that
70x+73y=71x+71y
it gives us x=2y
so ratio will be 1:2
