A. gained $10101
B. gained$20202
C. lost $10101
D. lost $20202

Answer 1

sold two flats for $999999 each

that means get received 999,999 on the one he lost 10%
0.9*x = 999,999
we can can find x.
x= 999,999/0.9
he lost 10% of x
0.1*x = 0.1/0.9 * 999,999
= 1/9 * 999,999 = 111,111 lost

Answer 2

\[ 999999\times (1.1)-999999\times .9\]

Answer 3

but there're only two values for us to choose: 10101 and 20202

Answer 4

he received 999,999 on the one he made 10%
1.1x= 999,999
x= 999,999/1.1
he made 10% of this
0.1 x = 999,999/11 = 90,909 gained

Answer 5
