a) What sum of money should be invested for 5 years at 8% p.a. to earn the simple interest same as Rs. 3600 at 10% p.a for 4 years?


[Hint : Answer is Rs. 9000]

Answer 1

P= ?, R= 8%p.a., T= 5 yrs, P'= ?, R'= 10% p.a. , T'= 4 yrs

Now, P=P'

⇒(P×R×T)÷100=3600=(P'×R'×T')÷100                                             ------------(1)

From Eqⁿ (1)

⇒(P×R×T)÷100=3600

⇒P×8×5=360000

⇒P = 9000                                                               (dividing 360000 by 40)

Since P= P'

P=P'= rs. 9000

Answer 2

Hi mukheer ! Here is your answer :)

☆Given☆

⟹ P= ?

⟹ R= 8%p.a

⟹ T= 5 yrs

⟹ P'= ?

⟹ R'= 10% p.a.

⟹ T'= 4 yrs

Now, P=P'

⟹ $\frac{p \times r \times t}{100} = 3600$ (1)Equation

From Eqⁿ (1)

⟹ $\frac{p \times r \times t}{100} = 3600$

⟹ $p \times 8 \times 5 = 3600$

⟹ $p = \frac{3600}{40}$

⟹ $p = 9000$

⟹ ${p}^{} = {p}^{1}$

Since the answer is 9000.
