Question

a sum of money amounts to 1380 in 3 years at 5% per anum. find the sum .with steps​

Answer 1

Answer:

Amount = ₹1587

Step-by-step explanation:

Given :

Principal = 1380

Time = 3 years

Rate = 5%

To find :

Sum of money (Amount)

Taken :

First find the simple interest -:

$\boxed{\sf{S.I.=\dfrac{P+R+T}{100}}}$

Where,

S.I. = Simple intrest

P = Principal

R = Rate

T = Time

After that to find the amount use this formula -:

$\boxed{\sf{A=S.I.+P}}$

Where,

A = Amount

Solution :

Simple intrest -:

$:\implies\sf{S.I.=\dfrac{1380\times5\times3}{100}}$

$:\implies\sf{S.I.=69\times3}$

$:\implies\sf{S.I.=207}$

Amount -:

$:\implies\sf{A=1380+207}$

$:\implies\sf{A=1587}$

So , the amount is ₹1587 .

Answer 2

Given :

• Principal = 1380
• Time = 3 years
• Rate = 5%

To find :

• Amount

Solution:

First find the simple interest -:-

★ S.I. = P + R + T/100

Where,

• S.I. = Simple intrest
• P = Principal
• R = Rate
• T = Time

Putting the values:-

→ S.I. = 1380 × 5 × 3/100

→ S.I. = 69 × 3

→ S.I. = 207

Then we find the amount :-

★ A = S.I. + P

Putting the values:-

→ A = 1380 + 207

→ A = 1587

Hence,

• The amount is ₹1587 .
