Far easier to utilise subsitituion in this case.
Let 2003 income be 10
Her 2004 income will therefore be 12.
Solving for 12/10 gives us 6 to 5.

Because Aisha’s income in 2004 was 20% greater than her income in 2003, her income in 2004 was equal to
(100% of her income in 2003) + (20% of her income in 2003) which is 120% of her income in 2003. Therefore, the ratio of her income in 2004 to her income in 2003 is 120 to 100, which is equivalent to 6 to 5.
The correct answer is Choice C.
Alternatively, to say that Aisha’s income in 2004 was 20% greater than her income in 2003 is the same as saying that her income increased by 1/5. Therefore, her income in 2004 was 6/5 of her income in 2003, and the ratio of her income in 2004 to her income in 2003 is 6 to 5.
The correct answer is Choice C.
