Answer 1

Step-by-step explanation:

p=25000

r=15%pa

t=2yrs

S.I

$p \times r \times t \div 100$

$25000 \times15 \times 2 \div 100 \\ans \: is \: 75000$

$25000(1 + 15 \div 100)^{2} \\ the \: ans \: is \: 38021.875$

as the S.I will be having more interest.

Answer 2

Given:-

• Principal (P) = 25000
• Rate interest (R) = 15%
• Time (t) = 2 years

Find:-

Money gained by Ravi during a transaction.

Solution:-

Interest that Ravi has to pay :

$\sf{Simple\: Interest\: = \:\dfrac{P\:\times\:R\:\times\:T}{100}}$

$\implies\:\sf{\dfrac{25000\:\times\:15\:\times\:2}{100}}$

$\implies\:\sf{7500}$

Interest that Ravi receive :

$\sf{Amount\:=\:P\bigg(1 + \dfrac{R}{100}\bigg)^{t}}$

$\implies\:\sf{A\:=\:25000\bigg(1+\dfrac{15}{100}\bigg)^{2}}$

$\implies\:\sf{A\:=\:25000\bigg(\dfrac{115}{100}\bigg)^{2}}$

$\implies\:\sf{A\:=\:25000(1.15)^2}$

$\implies\:\sf{A\:=\:25000(1.3225)}$

$\implies\:\sf{A\:=\:33062.5}$

Interest that Ravi receive from Shishir = Amount - Principal

= 33062.5 - 25000

= 8062.5

Gain = 8062.5 - 7500

= 562.5

•°• Ravi gains Rs. 562.5 in this transaction.
