Question

Nalini borrowed rupees 550 from her friend at 8% per annum she returned the amount after 6 months how much did she pay ​

Answer 1

Answer:

principal (P)= Rs 550

rate of interest = R=8%

time =T=6 months =1/2 yr

Amount she has to pay = P(1 +TR/100)

= 550(1 + 8/200)

=550*(1+1/25)

=550*26/25

=22×26

=564

amount =Rs 564

Answer 2

GivEn:

• Nalini borrowed rupees 550 from her friend at 8% per annum she returned the amount after 6 months.

⠀⠀⠀⠀⠀⠀⠀

To find:

• How much did he pay?

⠀⠀⠀⠀⠀⠀⠀

SoluTion:

⠀⠀⠀⠀⠀⠀⠀

$\bf Here \begin{cases} & \text{Principal = Rs. 550 } \\ & \text{Time = 1/2 years} \\ & \text{Rate = 8\% per annum} \end{cases}$

⠀⠀⠀⠀⠀⠀⠀

we know that,

⠀⠀⠀⠀⠀⠀⠀

$\star\;{\boxed{\sf{\purple{ \dfrac{P \times R \times T}{100}}}}}$

⠀⠀⠀⠀⠀⠀⠀

$\small\sf\;\;\;\;\:\underline{Putting\;values\;:}$

⠀⠀⠀⠀⠀⠀⠀

$:\implies\sf \dfrac{55 \cancel{0} \times 1 \times \cancel{8}}{10 \cancel{0} \times \cancel{2}}$

⠀⠀⠀⠀⠀⠀⠀

$:\implies\sf \dfrac{55 \times 4}{10}$

⠀⠀⠀⠀⠀⠀⠀

$:\implies{\underline{\boxed{\sf{\pink{Rs.\;22}}}}}\;\bigstar$

━━━━━━━━━━━━━━━

⠀⠀⠀⠀⠀⠀⠀

Now, we have to find amount she paid,

⠀⠀⠀⠀⠀⠀⠀

$\star\;{\boxed{\sf{\purple{Amount = P \times S.I.}}}}$

⠀⠀⠀⠀⠀⠀⠀

$:\implies\sf 550 + 22$

⠀⠀⠀⠀⠀⠀⠀

$:\implies{\underline{\boxed{\sf{\pink{Rs. 572}}}}}\;\bigstar$

⠀⠀⠀⠀⠀⠀⠀

$\therefore$ She paid Rs. 572.
