Question

find the principal that will yield an interest of rupees 680 in 4 years at 8% per annum.

Answer 1

Heya mate, Here is ur answer


SI=680


Time =4 years


Rate =8% P.A


Principle=?


We know that



Simple Interest=Principle×Time ×Rate /100



Keeping the values in the formula


$680 = \frac{principle \times 4 \times 8}{100}$


Taking the constant other side


$\frac{680 \times 100}{4 \times 8} = principle$


$2125 = principle$



$<b><u>So, the principle that will yield an interest of ₹680 in 4 years at 8% per annum is ₹ 2125 .</u></b>$

Answer 2

Hey !!





Rate of interest ( R ) = 8 %



Simple interest ( S.I ) = 680




Time ( T ) = 4 years.


Principal ( P ) = ?


We know that,

S.I = P × R × T /100



680 = P × 8 × 4 / 100




32 P = 68000



P = 68000/32


P = 2125.



Hence,


Principal =2125.
