Question

a number is such that it is as much greater than 560 as it is less than 894 find 3/7 of the number

Answer 1

$<b> >>> First Method: <<<</b>$

Let that number is x.

Now from given question,
Let x is z more from 560 and z less from 894.

So,
x = 560 + z
x = 894 - z

Adding both equations, we get,

x + x = 560 + z + 894 - z
2x = 560 + 894
2x = 1454
x = 727

Now 3x/7 = (3/7)(727) = (2181/7) = 311.57

$<b> >>> Second Method: <<<</b>$

As a number is the same amount greater and lesser than given two numbers, we can say that the required number will be average of them,

x = (560 + 894)/2

rest process is same as above first method.
