Answer:
Capacity of 60000 litres "to 1 significant figure" means that lower bound is 54449, upper bound is 64999.
=> 10% of that capacity is more than 54449/10 = 5444.9 litres
Tony pours in 5400 litres of water "to 2 significant figure" means that lower bound is 5349, upper bound is 5444.
Because 5444<5444.9, then clearly he is not correct when he said " I have filled more than 10% of the container"
did u find out the answer bc I'm failing math like really badly aha ✋

Answer:There are 72 heads (chicken and rabbit) and 200 legs. How many chickens and rabbits are present totally?
Step-by-step explanation
There are 72 heads (chicken and rabbit) and 200 legs. How many chickens and rabbits are present totally?
Legs of a chicken = 2
Legs of a rabbit = 4
Total heads = 72
Total legs= 200
Let's assume that each of them has minimum 2 legs.
So 72*2 = 144 legs
Remaining legs: 200-144= 56
These remaining legs belong to rabbit because rabbit has 4 legs each.
2*Rabbits= 56
Rabbits= 56/2 = 28
Out of 72, 28 are rabbits. So there are 72-28= 44 chicken.
