Question

rs.5500 amounts to 7975 in 5 years at simple interest .what will rs.6200 amount to in 3 years at the same rate of interest????

Answer 1

$\textbf{\large{\underline{Answer :}}}$

$\textbf{\large{\underline{Rs.7874}}}$

Rs. 6200 will Amount to Rs. 7874 in 3 years at the same rate of interest.

★ Explaination :

Here :

• Principal (P) = Rs. 5500
• Time (T)= 5 years
• Amount(A) = Rs. 7975

$\therefore$ SI = Amount - Principal

$= > 7975 - 5500 = 2475$

$We \: know \: SI \: = \frac{P \times R\times T}{100}$

$= > 2475 = \frac{5500 \times R \times 5}{100}$

$= > \frac{2475 \times 100}{5500 \times 5} = R$

$= > R \: = \frac{2475 \times 100}{5500 \times 5}$

$= > \frac{2475}{275}$

$= > R \: = \: 9$

$\large{\green{\boxed{\green{\boxed{\red{\textsf{R = 9 percent}}}}}}}$

$\therefore$ R = 9%

Now :
P = Rs.6200
R = 9% ( from above )
T = 3 years

$\therefore$ SI =

$= > \frac{prt}{100} = \frac{6200 \times 9 \times 3}{100}$

$= > 62 \times 9 \times 3$

$= > 558 \times 3$

$= > 1674$

$\large{\green{\boxed{\green{\boxed{\red{\textsf{Rs.1674}}}}}}}$

→ Amount = P + SI

$= > 6200 + 1674$

$= > 7874$

$\large{\green{\boxed{\green{\boxed{\red{\textsf{Rs. 7874}}}}}}}$

$\therefore$ Rs. 6200 will Amount to Rs. 7874 in 3 years at the same rate of interest.
