Quantitative Aptitude ( CCS) Mixed Chart

Directions- The following pie chart shows the distance travelled by boat on different days. The speed of the stream is same in both upstream and downstream direction. The table shows the speed of stream at different days. Study the data given carefully and answer the questions based on it.

Days	Speed of the stream (km/hr)
Sunday	2
Monday	3
Tuesday	2.5
Wednesday	-
Thursday	2

If the total speed of a boat in still water on Sunday and Tuesday is 12.5 km/hr and also time taken to cover the downstream distance on Sunday is equal to the time taken to cover the upstream distance on Tuesday. Find the ratio of speed in still water on Sunday and Tuesday.

Explanation:

Let speed of boat on Sunday =u
Speed of boat on Tuesday = v
(u + v)=12.5km/hr
According to question
(v+2)/ (u-2.5) = 15% of 360/18%of 300
(Time same so ratio of speed = ratio of dist.)
V+2= u-2.5
u -v= 4.5
u=8, v=4.5
Therefore u: v = 16:9
