The ratio of the earnings of P and Q is 9:10. If the earnings of P increases by one-fourth and the earnings of Q decreases by one-fourth, then find the new ratio of their earnings? Choose the correct option.
A) 2/3 B) 3/2 C) 4/5 D) 5/8 E) 4/2
Let the earnings of P and Q be 9x and 10x respectively.   New ratio = [9x + 1/4 (9x)]/[10x - 1/4 (10x)]   =&gt; 9*(1 + 1/4)/10*(1 - 1/4)   =&gt; 9/10 * (5/4)/(3/4) = 3/2   Answer:3/2
