Question

find the amount and the first question rupees 525 for 3 years at 3 % per annum

Answer 1

$\underline{\underline{\Huge\mathfrak{Solution ;}}}$

Given ;-
• Amount = ₹ 525
• Time = 3 years
• Rate = 3% p.a.

Now ,
We know that ;
• SI = P × R × T / 100

So ,

$= > \frac{525 \times 3 \times 3}{100}$

$= >47.25$

Than ,
Amount = P + SI
=> ₹(525 + 47.25 )
=> ₹572.25

Hence ,
The amount = ₹572.25

Answer 2

Answer : -

The amount is Rs.572.25

Explaination :

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

$\large = > \frac{525 \times 3 \times 3}{100}$

$\large = > \frac{105 \times 9}{20}$

$\large= > \frac{21 \times 9}{4}$

$\large= > \frac{189}{4}$

Divide them ,

$= > 47.25$

According to the formula :

=> Amount = Principal + Simple Interest

=> 525 + 47.25

=> $\large{\green{\boxed{\green{\boxed{\red{\textsf{ Rs.572.25 }}}}}}}$

$\therefore$The amount is Rs.572.25
