Right now, Al and Eliot have bank accounts, and Al has more money than Eliot. The difference between their two accounts is 1/12 of the sum of their two accounts. If Al’s account were to increase by 10% and Eliot’s account were to increase by 20%, then Al would have exactly $21 more than Eliot in his account. How much money does Eliot have in his account right now? Options:
A) $110  B) $120  C) $180  D) $220  E) $210
Lets assume Al have amount A in his bank account and Eliot's bank account got E amount. We can form an equation from the first condition.   A-$210 = 1/12*(A+$210) ==&gt; 11A = 13$210 ------------ (1)   Second condition gives two different amounts, Al's amount = 1.1A and $210liot's amount = 1.2$210   1.1A = 21 + 1.2$210 ==&gt; 11A =210 +12$210 -------(2)   Substituting (1) in (2):   13$210 = 210+12$210 ==&gt;$210 = 210   $210
