A money lender lent a total of $1600 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 $1600, how much did he lend to each of the two customers? Choose the most appropriate option:  A) 700; 1100  B) 1072; 528  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 + (1600-x)*6/100 = 1600*5.67/100   Simplifying we get x= 528   1072; 528
