CP is C after 3 years SP is 5/4 of C. Profit is C/4. 50% of C/4 is C/8

The gain = 0,25C = C/4 => tax = 50% * C/4 = C/8

Choosing values is quick here.

Ms. Jones paid C = \$100 for the house

She sold it for 25 percent more than she paid for it. She sold it for:
\$100 * 1.25 = \$125

She pays 50 % tax on the gain.
The gain: \$125 - 100 = \$25 gain

The tax on the gain:
\$25 * .50 = \$12.50

With C = 100, find the choice that yields answer 12.50

Eliminate C, D, and E immediately:
(C) C/4
(D) C/2
(E) 0.6C
They're too large (\$25, \$50, and \$60 respectively)

(A) C/24
100/24 is a lot less than 12.50. 100/25 = 4, so 100 divided by 24 will not be much greater than 4. Eliminate Answer A.

(B) C/8
100/8 = 12.50
That is a match
