their speeds in still water?Correct
Answer – 1) 4:5
Explanation
Downstream speed of boat A = a+s
Downstream speed of boat B = b+s
Upstream speed of boat A = as
Upstream speed of boat B = bs
Then
(as):(bs) = 2:3
S= 3a2b (1)
And (a+s): (b+s) = 6:7
S = 6b 7a (2)
From 1 and 2
A:B =4:5Incorrect
Answer – 1) 4:5
Explanation
Downstream speed of boat A = a+s
Downstream speed of boat B = b+s
Upstream speed of boat A = as

(as):(bs) = 2:3
S= 3a2b (1)
And (a+s): (b+s) = 6:7
S = 6b 7a (2)
From 1 and 2
