Answer:
the world’s a stage,
And all the men and women merely players;
They have their exits and their entrances,
And one man in his time plays many parts,
His acts being seven ages. At first, the infant,
Mewling and puking in the nurse’s arms.
Then the whining schoolboy, with his satchel
And shining morning face, creeping like snail
Unwillingly to school. And then the lover,
Sighing like furnace, with a woeful ballad
Made to his mistress’ eyebrow. Then a soldier,
Full of strange oaths and bearded like the pard,
Jealous in honour, sudden and quick in quarrel,
Seeking the bubble reputation
Even in the cannon’s mouth. And then the justice,
In fair round belly with good capon lined

mark me as brain list power
Step-by-step explanation:
we know that the simple interest formula is
PRT/100, where P is the principle sum, R is the rate of interest and T is the time.
ACCORDING TO QUESTION
Interest 1 = Interest 2
450 x 3 x 3/100 = P x 4.5 x 3 /100
cancelling 3/100 from both sides, we get
450 x 3 = P x 4.2
P = 450/4.2 x 3
P = 300
