Darrell and Allen's ages are in the ratio of 7:11. If their total age now is 162, calculate Allen's age 10 years from now.
The total ratio representing their ages is 7+11= 
<gadget id="calculator">7+11</gadget>
<output>18</output>
18.
Since the fraction of the ratio that represents Allen's age is 11/18, Allen's current age is 11/18*162 = 
<gadget id="calculator">11/18*162</gadget>
<output>99</output>
99.
If Allen is currently 99 years old, in 10 years he will be 99+10 = 
<gadget id="calculator">99+10</gadget>
<output>109</output>
109 years old.
