Answer:
the amount of interest = 405 000
the amount she has to pay = 405 000 + 180000 = 585 000
Step-by-step explanation:
We make use the simple interest formula
PRT/100
P is the principle
R is the rate
T is the time
180 000 * 7.5 * 30
= 40 500 000 / 100
= 405 000
the amount of interest = 405 000
the amount she has to pay = 405 000 + 180000 = 585 000
