If Rs. 4

9000 is invested at 8% p.a. simple interest for 5 years, find the interest.

Sol: simple interest formula: 9000 × 8 × 5/100 = Rs. 3600

Answer 2

Given :

• Rate = 12% p.a.
• Interest = ₹9000
• Time = 2 years

To find :

Money invested (Principal)

Procedure :

• We are given Interest (simple interest) on a particular money with given rate and time period
• using these information we need to find the money invested

Formula used :

I = Prt

Here,

• I = interest
• P = principal
• r = rate
• t = time

Solution :

$\sf \implies \: 9000 = \dfrac{ P \times \: 12 \times 2}{100} \\ \\ \sf \implies \: P \: = \: \dfrac{9000 \times 100}{12 \times 2} \\ \\ \sf \implies \: P \: = \: 375 \times 100 \\ \\ \sf \implies \: P \: = \: \bold{37500}$

ANSWER :

Money invested = ₹37500
