@mod plz check my doubt
What’s that 5 there in ques 4′ solution
No
5 not to be included
typo
plzz tell 2 ques B=10 kaise aya?
B is 50% more efficient
So A : B = 2 : 3
So days 3 : 2
A = 3 = 15
So B = 2 = 10
in 5 ques why 1.6*2?
down speed = 16 (as calculated )
now
stream speed = (down-up)/2
1.6=(16-up)/2
up=12.8
hope it helps
