Question

plzzzzz help me out........ ​

Answer 1

$\sf{\bold{\blue{\underline{\underline{GiveN :}}}}}$

Principle = Rs. 1800

Rate = 5%

Time = 1 year

$\sf{\bold{\blue{\underline{\underline{To\:Find :}}}}}$

Simple interest = ??

Amount = ??

$\sf{\bold{\blue{\underline{\underline{Solution :}}}}}$

${\red{\boxed{\frak{SI = \dfrac{p\times r\times t}{100}}}}}$

⠀⠀⠀⠀

$\sf: \implies\: {\bold{ SI =\dfrac{ 1800\times 5 \times 1}{100}}}$

⠀⠀⠀⠀

$\sf: \implies\: {\bold{ SI ={ 18\times 5 \times 1}}}$

⠀⠀⠀⠀

$\sf: \implies\: {\bold{ SI ={ 18\times 5}}}$

⠀⠀⠀⠀

$\sf: \implies\: {\bold{ SI = Rs. 90}}$

⠀⠀⠀⠀

${\red{\boxed{\frak{Amount = Principle + Simple\: Interest}}}}$

⠀⠀⠀⠀

$\sf: \implies\: {\bold{ Amount = Rs.1800 + Rs. 90}}$

⠀⠀

$\sf: \implies\: {\bold{ Amount = Rs.1890}}$

Therefore:—

Rs. 1800 will amount to Rs. 1890 in 1 year at 5% per annum

Answer 2

$\sf{\bold{\red{\underline{\underline{Given :-}}}}}$

Principle = Rs. 1800

Rate = 5%

Time = 1 year

$\sf{\bold{\green{\underline{\underline{To\:Find :-}}}}}$

Simple interest = ??

Amount = ??

$\sf{\bold{\pink{\underline{\underline{Solution :-}}}}}$

${\purple{\boxed{\frak{SI = \dfrac{p\times r\times t}{100}}}}}$

⠀⠀⠀⠀

$\sf: \implies\: {\bold{ SI =\dfrac{ 1800\times 5 \times 1}{100}}}$

⠀⠀⠀⠀

$\sf: \implies\: {\bold{ SI ={ 18\times 5 \times 1}}}$

⠀⠀⠀⠀

$\sf: \implies\: {\bold{ SI ={ 18\times 5}}}$

⠀⠀⠀⠀

$\sf: \implies\: {\bold{ SI = Rs. 90}}$

⠀⠀⠀⠀

${\purple{\boxed{\frak{Amount = Principle + Simple\: Interest}}}}$

⠀⠀⠀⠀

$\sf: \implies\: {\bold{ Amount = Rs.1800 + Rs. 90}}$

⠀⠀

$\sf: \implies\: {\bold{ Amount = Rs.1890}}$

Therefore:-

Rs. 1800 will amount to Rs. 1890 in 1 year at 5% per annum
