Answer:
726.240 litre
Step-by-step explanation:
1000ml = 1 litre
726240ml = 726240/1000
=726.240litre
If x ≡ 7 (mod 20), then
x ≡ 7 ≡ 27 ≡ 47 ≡ 67 ≡ 87 ≡ … (mod 20)
or equivalently, x = 7 + 20k for some integer k.
Taken mod 4, we have
x ≡ 7 + 20k ≡ 3 (mod 4)
and mod 5,
x ≡ 7 + 20k ≡ 2 (mod 5)
so that a = 3 and b = 2.
