a. 15,20 min
b. 15,10 min
c. 10,15 min
d. 25,20 min
also explain along with answer ..
Unconventional method. Option b and d are ruled out, because its given B takes 5 hours more.
Option A and D left. In such cases just check {xy/(x+y)} gives value 6. which is 10,15, that is our answer.
why {xy/(x+y)}??? Because if u gonna make equation in conventional way, it will be :-
1/x+ 1/y = 1/z ; here in this question z=6 given and also y = x+5
1/x+ 1/y = 1/z; z= xy / (x+y)...i guess i made it clear....
