Answer:
6 litres of water did the barrel have after the thunder storm.
Step-by-step explanation:
Before thunder storm barrel contained water=4 litre
After thunderstorm barrel contained water= 6 litre
⇒6 litre/24 hr=0.25 litre per hour
0.25 litres per hour for 8 hr
⇒0.25 x 8=2 litre in 8 hr
Add the 2 litre from thunderstorm on to the original amount in the barrel,4 litre
=2+4
= 6 litre
∴6 litres of water did the barrel have after the thunderstorm.
