Answer:
3780
Step-by-step explanation:
S-1
money @of 12% = 3000
money@of 15%= 9000-3000
= 6000
TIME:- 3 YRS
S-2
We know that
SI= PRT/100
where,
SI:- SIMPLE INTEREST
P:-PRICIPAL AMMOUNT
R:- RATE OF INTEREST
T:-TIME OF INTEREST
as we know that total ammount is divided into two different amounts with different rate of interest
therefore,
Total interest
SI= SI' + SI"
SI' :- 3000*3*12/100
SI':- 1080
SI":- 6000*3*15/100
SI":- 2700
SI= 1080+2700
SI= 3780
hence total interest for three years is 3780
