Marks: +1, -0

The places P and Q are 27 km away. Two trains with speeds of 24 km/hr and 18 km/hr respectively start simultaneously from P and Q and travel in the same direction. They meet at a point R beyond Q. The distance QR is:

126 km
81 km
48 km
36 km

Validate

Solution:

Speed is 24 km/h and 18 km/h respectively. Let the distance between QR is x km.
According to the statement,

x/{18}

{x+27}/{24}

24x = 18x + 484
24x - 18x = 484
6x = 484
x =

{484}/6

= 81 kms
