A money lender lent a total of $1700 to two of his customers. He charged at the rate of 5%p.a. to one of them and 6% p.a. to the other. If he earned an average of 5.67% on $1700, how much did he lend to each of the two customers?  Answers
A) 700; 1100  B) 1139; 561  C) 1000; 800  D) 1200; 800  E) None of the above
The method given above is the one given in the book.   However the method I used was   (1*x*5)/100 + (1700-x)*6/100 = 1700*5.67/100   Simplifying we get x=561   1139; 561
