There will be 2 series for given question:

12, -24, -48, -96........... to infinity

6, -3, -3/2, -3/4....... to infinity

Explanation:

answer:

answer is 21 ltr

step-by-step explanation:

let a=7x

b=5x

so, the mixture is 7x+5x=12x

when, 9 ltrs drained then

12x-9

then the can is filled with b(9x)

so, atq

12x-9=9x

12x-9x=9

3x=9

x=3

so, a present initially =7*3=21

the answer is 21 litre.
