Question

fi the simple interest and amount principal is equal to Rupees 10000 rate is equal to 18% time is equal to 7 years find the amount and simple interest answer​

Answer 1

Answer:

simple interest=12600rs

amount=22600rs.

Step-by-step explanation:

simple interest=PRT/100

                    =10000*18*7/100

                    =  100*126  

                     =12600rs.

amount=12600+10000

            = 22600rs

Answer 2

GIVEN :-

• Principal (P) = Rs. 10000
• Time (T) = 7 years
• Rate % = 18 %

TO FIND :-

• Simple interest (S.I)
• Amount (A)

SOLUTION :-

$\dag \boxed{ \red{ \bf \:S.I = \dfrac{P \times R \times T}{100}}}$

★ Substitute the given values,

$\implies \sf \dfrac{100\cancel {00 }\times 18 \times 7}{\cancel{100}} \\ \\ \implies \sf 100 \times 18 \times 7 \\ \\ \implies \underline {\boxed{\sf \blue{ S.I = 12600 }}}$

❏ Hence the simple interest is Rs. 12600.

$\dag \boxed {\red{\bf Amount(A) = P + S.I}} \\ \\ \implies \sf 10000 + 12600 \\ \\ \implies \underline {\boxed{\blue{\sf Amount(A) = 22600}}}$

❏ Hence the Amount is Rs. 22600.

ADDITIONAL INFORMATION :-

$\bf{ \underline{Some Formulae}} \\ \\ \rightarrow \quad \sf P = \dfrac{100 \times S.I}{R \times T} \\ \\ \\ \rightarrow \quad T = \dfrac{100 \times S.I}{P \times R} \\ \\ \\ \rightarrow \quad R = \dfrac{100 \times S.I}{P \times T} \\ \\ \\ \rightarrow \quad A = P + S.I \\ \\ \\ \rightarrow \quad S.I = \dfrac{P \times R \times T}{100}$
