If the total distance is increased by 44 then find the ratio of time taken by boat E in upstream to ...........

Quantitative Aptitude (SBI-PO) 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 total distance is increased by 44% then find the ratio of time taken by boat E in upstream to cover new distance that of by boat A in downstream to cover old distance.

Explanation:

Speed = Distance / Time
New Distance = 2000 × 144%
= 2880 km
Time taken by boat E to cover new distance (upstream) = (2880 × 22% ) / 16
= (18 × 11 ) / 5 hours
Time taken by boat A to cover old distance (downstream) = 500/36
= 125/9 hours
Ratio of times
(18 × 11 ) / 5 : 125/9
after simplifying we get
1782 / 625

Hence, option 4 is the correct answer.
