Question

sheela borrowed a sum of ₹10000 from leena at 7% per annum. find the interest and amount to be paid at the end of two years​

Answer 1

Answer:

Sheela will return Rs. 11,400 including the interest of Rs. 1400 at the end of 2 years.

Step-by-step explanation:

Sheela borrowed = Rs. 10,000

Rate = 7%

Interest at the end of = 2 years

Amount and interest = ??

Using the formula:

$\boxed{\sf{SI = \frac{Principal \times Rate \times Time}{100}}}$

• Principal = Rs. 10,000
• Rate = 7%
• Time = 2 years

$\sf{\longrightarrow \: {SI = \dfrac{10000\times 7 \times 2}{100}}}$

$\sf{\longrightarrow \: {SI = \dfrac{100\times 14}{1}}}$

$\sf{\longrightarrow \: {SI =100 \times 14}}$

$\sf{\longrightarrow \: {SI =1400}}$

Interest = Rs. 1400

_____________________

$\boxed{\sf{Amount = Principal + Simple \: Interest}}$

• Principal = Rs. 10,000
• Simple Interest = Rs. 1,400

$\sf{\longrightarrow \: Amount = 10000 + 1400}$

$\sf{\longrightarrow \: Amount = 10000 + 1400}$

$\sf{\longrightarrow \: Amount = 11400}$

Therefore, Sheela will return Rs. 11,400 including the interest of Rs. 1400 at the end of 2 years.

Answer 2

Given :

• Sheela borrowed a sum of ₹10000 [ Principal ]
• Rate of Interest is 7 % [ Rate of Interest ]
• Interest at the end of 2 yrs [ Time ]

Exigency To Find : Interest & Amount.

⠀⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━⠀⠀⠀⠀

⠀⠀━━ Finding Interest :

$\dag\:\:\it{ As,\:We\:know\:that\::}$

$\qquad \dag\:\:\bigg\lgroup \sf{ Simple \:Interest \:\:: \dfrac{ P \times R \times T }{100} }\bigg\rgroup$

⠀⠀⠀⠀⠀Here , P is the Principal , R is the Rate of Interest & T is the Time .

⠀⠀⠀⠀⠀⠀$\underline {\boldsymbol{\star\:Now \: By \: Substituting \: the \: known \: Values \::}}$

$\qquad :\implies \sf Interest = \dfrac { 10,000 \times 7 \times 2 }{100}$⠀

$\qquad :\implies \sf Interest = \dfrac { 10,0\cancel {00} \times 7 \times 2 }{\cancel {100}}$⠀

$\qquad :\implies \sf Interest = 100 \times 7 \times 2$⠀

$\qquad :\implies \sf Interest = 700 \times 2$⠀

$\qquad :\implies \frak{\underline{\purple{\:Interest = Rs.1400\:\: }} }\bigstar$

Therefore,

⠀⠀⠀⠀⠀$\therefore {\underline{ \mathrm {\:Interest \:is\:\bf{Rs. \:1400}}}}$

⠀⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━⠀

⠀⠀━━ Finding Amount :

$\dag\:\:\it{ As,\:We\:know\:that\::}$

$\qquad \dag\:\:\bigg\lgroup \sf{ Amount \:\:: Interest + Principal }\bigg\rgroup$

⠀⠀⠀⠀⠀Here , Interest is Rs. 1400 & Principal is Rs. 10,000

$\qquad :\implies \sf Amount = 1400 + 10,000$⠀

$\qquad :\implies \frak{\underline{\purple{\:Amount = Rs.11,400 \:}} }\bigstar$

Therefore,

⠀⠀⠀⠀⠀$\therefore {\underline{ \mathrm {\:Amount \:is\:\bf{Rs. \:11,400}}}}$
