Question

At what rate percent will a sum of rs1200 amount to rs1600 in 6 years

Answer 1

$amount = \frac{p \times r \times t}{100}$
Where, p = principal
r = rate of interest
t = time

$1600= \frac{1200 \times r \times 6}{100} \\ \frac{1600 \times 100}{1200 \times 6} = r$
rate of interest = 2.22 ℅

Answer 2

Answer:

Rate Percent = 50/9%

Step-by-step explanation:

According to the Question,

Given,

Principal= Rs 1200

Amount= Rs 1600

Time = 6 year

Rate= ?

Simple Interest= Rs 400

Use formula,

Simple Interest= P*R*T/100

400= 1200*R*6/100

Rate = 50/9%

Hence, the rate percent is 50/9 % at which the sum Rs 1200 amount to Rs 1600.
