-) A water tap A takes 7 minutes more than water tap B for filling up a tank with water.
The tap A takes 16 minutes more than the time taken by both the taps together to fill
the tank. Find the time each tap alone would take to fill the tank.​

Answer 1

Answer:

let the time taken by tap a be x min. and by tap b be y min.

We know

x = 7+y...........(1)

and

x=16+(x+y)...........(2)

but,

for 2 objects doing one work,

time taken by both two object in whole= (time excess taken by one object than other+ time excess taken by same in whole)/2+1 /2

here,

x+y= (7+16)/2+1/2

=23/2+1/2

=24/2

x+y=12

put x+y=12 in (2)

x= 16+12

x=28

time taken by tap a is 28 min

now

put x=28 in (1)

so,

28-7=y

y=21

time taken by tap b is 21min
