Given :- Ramenbabu Mate deposited Rs 370,000 in three banks. The annual simple interest rates of the three banks are 4%, 5% and 6% respectively; After 1 year, the amount of interest in his three banks is equal.
To Find :- Let's calculate how much money he had deposited in the three banks. ?
Answer :-
we know that, when simple interest is same ,
- Ratio of amounts = 1/R1*T1 : 1/R2*T2 : 1/R3*T3
so,
→ A1 : A2 : A3 = 1/4*1 : 1/5*1 : 1/6*1
→ A1 : A2 : A3 = 1/4 : 1/5 : 1/6
→ A1 : A2 : A3 = (15 : 12 : 10)/60
→ A1 : A2 : A3 = 15 : 12 : 10 .
then,
→ A1 = (15/37) * 370000 = Rs.150000
→ A2 = (12/37) * 370000 = Rs.120000
→ A3 = (10/37) * 370000 = Rs.100000
