amu-5
ali-7
as they together build a pond in 12 days=24/2
thus considering ratio as x
5x+7x=12
12x=12
Thus x=1
ali-7
as they together build a pond in 12 days=24/2

5x+7x=12
12x=12
Thus x=1

Answer:
Amu can dig 1 pond in 20.5 days
& Ali can dig 1 pond in 28.8 days
Step-by-step explanation:
Considering x as common factor,
Amu-1pond= 5x days
Ali-1pond=7x days
Amu can dig 1/5x in 1 day and Ali can dig 1/7x in 1 day.
They together can dig (1/5x+1/7x) in 1 day.
By question, They can dig 1 pond in 12 days. That is they can dig 1/12 in 1 day.
Now,
1/5x + 1/7x = 1/12
=> 12/35x = 1/12
=> x = 144/35
Thus Amu can dig 1 pond in 5× 144/35 days i.e 20.5 days
& Ali can dig 1 pond in 7× 144/35 days i.e 28.8 days
