Ok, there are 5 soldiers, and people have 2 legs so the number of legs of the soldiers will be 5×2=10legs.
A tiger has four legs and there are 5 tigers, so there will be 5×4=20legs.
There are 5 small tigers with each tiger, so there will be 5×5=25little tigers. A little tiger has 4 legs and therefore, there will be 25×4=100legs.
Add them all up.
