Question

What number should be subtracted from 9000 so that the difference is 3571 ?

Answer 1

Given

Difference of two numbers = 3571

One of the numbers = 9000

Let the other number be x

Since the number should be subtracted from 9000,

9000 is the bigger number

9000 > x

$\implies 9000-x=3571$

Transposing a number, changes it signs,

Hence it becomes, -9000 here

$\implies -x=3571-9000$

$\implies -x=-5429$

Negative signs are cancelled.

$\implies x = 5429$

$\boxed{\boxed{\bold{Therefore, \ the \ other \ number \ is \ 5429}}}}}}}$

                                                       

Answer 2

Given ,

The difference between 9000 and number is 3571

Let , the unknown number be " x "

By the given condition ,

$</p><p>\sf \Rightarrow 9000 - x = 3571 \\ \\ \sf \Rightarrow </p><p>- x = 3571 - 9000 \\ \\ \sf \Rightarrow </p><p>- x = - 5429 \\ \\ \sf \Rightarrow </p><p>x = 5429$

$\therefore \bold{ \sf \underline{The \: unknown \: number \: is \: 5429}}$
