Question

An article costing rs 9000 is sold at a discount which is equal to the simple interest on rs 3000 for n months. if rate of discount is same as the rate of interest, the n will be…….months

Answer 1

so, n =3 is the answer for the que

Answer 2

Answer:

n = 3

Step-by-step explanation:

Let the rate of discount be r%

Cp of article = Rs.9000

Discount = r%

Discount = $\frac{r}{100} \times 9000$

Principal = Rs.3000

Time = n months

Rate of interest = r%

$SI = \frac{P \times R \times T}{100}$

$SI = \frac{3000 \times r \times n}{100}$

We are given that SP = Simple interest

$\frac{r}{100} \times 9000= \frac{3000 \times r \times n}{100}$

$9000=3000 \times n$

$n = 3$

Hence The value of n will be 3
