Question

A certain sum of money amounts to Rs. 5960 in four years at the rate of 6.25% p.a. . Find the principal amount.​

Answer 1

Answer:

The principal amount is Rs. 4768.

Step-by-step explanation:

The formula to find the interest  of a certain amount at a particular rate is,

$I=\dfrac{PNR}{100}$

where $I$ is the interest, $P$ is the principal amount, N is the number of years and R is the annual rate of interest. Using this we get the formula for accumulated amount as,

$A=P(1+\dfrac{RN}{100})$

where A is the accumulated amount.

It is given that the accumulated amount, A is 5960, The rate of interest R is 6.25, and the number of years N is 4.

Substitute these values in the formula for accumulated amount, we get,

$5960=P(1+\frac{6.25\times 4}{100}) = P\times 1.25\\\implies P=\dfrac{5960}{1.25}=4768$

So the principal amount is 4768 rupees.

Answer 2

QUESTION :

• A certain sum of money amounts to Rs. 5960 in four years at the rate of 6.25% p.a. . Find the principal amount.

GIVEN :

• amount = Rs. 5960

• time period = 4 years

• rate of interest = 6.25% p.a

TO FIND :

• Find the principal amount = ?

SOLUTION :

first we have formula :

• A = p ( 1 + RN/ 100)

then , we will multiply 6.25 with 4 and

divide with 100 we get

• 6 .25 × 4 /100 = 1.25

then, we will divide 5960 with 1.25 we get :

• = 5960/1.25 = 4768

so, principal we have = rs 4768
