Three friends rani, Bond and gokul divide $1107 amongs them in such a way that if $4, $6 and $8 are removed from the sums that rani, Bond and gokul received respectively, then the share of the sums that they got will be in the ratio of 2 : 4 : 10. How much did gokul receive?  Choices:	A) $170	B) $130	C) $150	D) $180	E) $174
Explanatory Answer   Let the sums of money received by A, B and C be x, y and z respectively.   Then x - 4 : y - 6 : z -8 is 2a : 4a : 10a   When $4, $6 and $8 are removed, we are removing a total of $18 from $1107.   Therefore, 2a + 4a + 10a = 1107 - 18= 
<gadget id="calculator">1107 - 18</gadget>
<output>1_089</output>
1089   i.e., 16a= 1089   or a = 68.   We know that z - 10 = 16a = 10 * 16= 
<gadget id="calculator">10 * 16</gadget>
<output>160</output>
160   Therefore, z= 160 + 10= 
<gadget id="calculator">160 + 10</gadget>
<output>170</output>
$170   The correct choice is ($170)
