On a stretch of water there is no current from P to Q but there is a current from Q to R. In such a circumstance, Vishal takes 3 hours to row downstream from P to R and 3 ½ hours upstream from R to P. Suppose the circumstances change and now the earlier current is there all the way from P to R. How long will Vishal take to row from R to P in the changed circumstances? 

  1. Ratio of the speed of Vicky in still water and that of the stream is 6 : 1.
  2. In the changed circumstances, his downward journey would have taken 2 ¾ hrs.

Explanation: We have the following information given M = hx, where h is the cost of a hen and x is the number of hens bought by him M = (n - 1) y, where (h - 1) is the cost of a pigeon and y is the number of pigeons bought by him M = (h - 2) z …..3) where (h - 2) is the cost of a parrot and z is the number of parrots bought by him. From I: M/h - 1 - M/h = 9/h - 2 or, y 0- x = 9z/M From II: x + y + z = 47 From all these, we get the answer that ther farmer bought 12 hens, 15 pigeons and 20 parrots.
