Answer 1

Answer:

500

Step-by-step explanation:

Let the original number be x

ATQ

( x - 10% of x ) + 10% of ( x - 10% of x ) = x - 5

( x - $\frac{x}{10}$ ) + ( 10% of ( x - $\frac{x}{10}$ ) ) = x - 5

( 9x/10 ) + ( 10% of 9x/10 ) = x - 5

( 9x/10 ) + ( 9x/100 ) = x - 5

9x/10  +  9x/100  = x - 5

90x/100 + 9x/100 = x - 5

99x = 100 ( x - 5 )

99x = 100x - 500

500 = 100x - 99x

500 = x

Therefore, the answer is 500
