If the simple interest on a sum of money at 6%p.a. for 7 years is equa...
**Answer:**
Given,
- Simple interest on a sum of money at 6%p.a. for 7 years = (2 x simple interest on another sum for 9 year at 5% p.a.)
Let's assume the sum of money for 7 years at 6% p.a. is P and another sum of money for 9 years at 5% p.a. is Q.
Then,
- Simple interest for P = (P x 6 x 7)/100
- Simple interest for Q = (Q x 5 x 9)/100
According to the question,
- (P x 6 x 7)/100 = 2 x (Q x 5 x 9)/100
Simplifying the above equation,
- P = (60/42)Q
- P/Q = 60/42
- P:Q = 20:14
- P:Q = 10:7
Therefore, the ratio of the sum of money for 7 years at 6% p.a. to another sum of money for 9 years at 5% p.a. is 10:7.

If the simple interest on a sum of money at 6%p.a. for 7 years is equa...
SI 1= P1*6*7/100
SI2 = P2*9*5/100
Therefore, 2(SI2)=SI1
2(P2*9*5/100) = P1*6*7/100
45/21 = P1/P2
15/7=P1/P2
The ratio is 15:7
