Hope its helps

Mark as brainiest please

Step-by-step explanation:

FOR MARY

PRINCIPAL= $200

RATE OF INTEREST = 5%

TIME = 3 YEARS

SIMPLE INTEREST = P*R*T/100

= 200*5*3/100 = 30

SIMPLE INTEREST = $30

ACCORDING TO QUESTION SI OF MARY = SI OF JOHN

FOR JOHN

PRINCIPAL = $300

RATE OF INTEREST = 5%

SIMPLE INTEREST = $30

TIME = SI*100/P*R = 30*100/300*5 = 2

THEREFORE TIME = 2 YEARS
