If the speed of boat G is 25 more than the speed of boat C and speed of stream for Boat G is 25 more...........

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%

If the speed of boat G is 25% more than the speed of boat C and speed of stream ( for Boat G) is 25% more than the speed of stream for boat B then find the difference (approx.) between time taken by boat G and boat C (both upstream) to cover the distance of 1240 km.

Explanation:

Speed = Distance / Time
Speed of boat G = 30 × 125%
= 37.5 km/hr
Speed of stream for boat G = 10 × 125%
= 12.5 km/hr
Time taken by boat G to cover 1240 km (upstream) = 1240 / (37.5 -12.5)
= 1240 / 25
= 49.6 hours
Time taken by boat C to cover 1240 km (upstream) = 1240 / 16
= 77.5
Difference in time = 77.5 – 49.6
= 28 hours ( Approx)

Hence, option 3 is the correct answer.
