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 choice from the following choices:
A) 3/6	B) 3/2	C) 3/9	D) 3/1	E) 3/5
Let the earnings of P and Q be Rs. 9x and Rs. 10x respectively.   New ration = [9x + 1/4(9x)]/[10x - 1/4(10x)]   =&gt; [9x(1 + 1/4)]/[10x(1 - 1/4)] = 9/10 * (5/4)/(3/4)   =&gt; 3/2.   Answer: 3/2
