Question

Find simple interest and amount on Rs8400 for 4 years at 8%per annum​

Answer 1

Answer:

in this question the principal amount is is 8400 time is 4 years and interest is 8% per annum so the simple interest is Principal X time x rate upon 100

( 8400 x 4 x 8) /100

84 X 32= 2688

the simple interest on amount 8400 for 4 years at 8% per annum is 2688.

Answer 2

Answer:

A1.

Data:

P = ₹8400

T = 4 years

R = 8%

\implies⟹ \sf{SI={\Large\frac{PTR}{100}} }SI=

100

PTR

\implies⟹ \sf{{\Large\frac{ 8400×4×8 }{ 100 }} }

100

8400×4×8

\implies⟹ \sf{84×4×8 }84×4×8

\therefore∴ \boxed{\sf{ SI= ₹2688 }}

SI=₹2688

\implies⟹ \sf{A=P + SI }A=P+SI

\implies⟹ \sf{ 8400+2688}8400+2688

\therefore∴ \boxed{\sf{A=₹11088 }}

A=₹11088

A2.

Data:

P = ₹9275

T = 2 years

R = 7 1/2% = 15/2%

\implies⟹ \sf{ SI={\Large\frac{PTR}{100}}}SI=

100

PTR

\implies⟹ \sf{{\Large\frac{9275×2×15 }{ 100×2 }} }

100×2

9275×2×15

\implies⟹ \sf{{\Large\frac{1885×15 }{ 20 }} }

20

1885×15

\therefore∴ \boxed{\sf{ SI = ₹1391.25 }}

SI=₹1391.25

\implies⟹ \sf{ A = P + SI}A=P+SI

\implies⟹ \sf{ 9275+1391.25}9275+1391.25

\therefore∴ \boxed{\sf{ A = ₹10666.25 }}

A=₹10666.25
