Quentin's income is 60% less than Sid's income, and Sam's income is 25% less than Quentin's income. If Sid gave 60% of his income to Sam and 40% of his income to Quentin, Quentin's new income would be what fraction of Sam's new income?  Choices
A) 8/9 B) 11/12 C) 8/13 D) 11/13 E) 12/13
We can take some easy numbers and make calculations simpler.   Let R ( Sid's income) = 100   Q (Quentin's income) = 40%R = 40   S (Sam's income) = 75% Q = (3/4)*40= 
<gadget id="calculator">(3/4)*40</gadget>
<output>30</output>
30   Now, if Sid gives 40% to Quentin --&gt; Q= 40 + 40= 
<gadget id="calculator">40 + 40</gadget>
<output>80</output>
80   60% given to Sam --&gt; S= 30+60= 
<gadget id="calculator">30+60</gadget>
<output>90</output>
90   The ratio is : Q/S= 80/90 = 8/9=8/9
