Time taken by boat A and C in downstream is approximately what percent more or less than time taken ...........

Quantitative Aptitude ( CCS) Data Table

Direction : Study the following Table and answer the questions that follow:

Boats	Speed of Boats (In km/hr)	Speed of Stream (In km/hr)	% Distance travelled (Total Distance = 2000km)
A	22	14	25%
B	26	10	15%
C	30	14	20%
D	21	13	18%
E	24	8	22%

Time taken by boat A and C (in downstream) is approximately what percent more or less than time taken by boat D ( in upstream) to travel their respective destinations

38.232% less

49.382% less

59.232% More

23.568 More

Explanation:

Speed = Distance / Time
Time taken by boat A ( in downstream) = 500 / 36
= 125/9 hour
Time taken by boat C ( in downstream) = 400/45
= 80/9 hour
Time taken by boat A + boat C = (125/9) + (80/9)
= 205/9 hour
Time taken by boat D ( in upstream) = 360 / 8
= 45 hour
Time taken by boat A and C (in downstream) is approximately what percent more or

less than time taken by boat D ( in upstream) = [ (205/9 – 45 ) / 45 ] × 100
= – 4000 / 81
= – 49.382 ( Approx)

Hence, option 2 is the correct answer.
