Question

What should be invested for 5 years at 8% per year to earn rs.136 simple interest?​

Answer 1

Answer:

340

Step-by-step explanation:

T=5 years

R=8%

I= Rs 136

we have

I=PTR/100

P=100I/TR

= (100*136)/(5*8)

=340

Answer 2

$Given \: Time (T) = 5 \: years$

$Rate \:of \: interest (R) = 8\%$

$Simple \: Interest (I) = Rs \: 136$

$Let \: Principal = P$

$P = \frac{ 100 \times I }{ TR }$

$\implies P = \frac{ 100 \times 136 }{ 5 \times 8 }$

$= Rs \: 340$

Therefore.,

$\red{ Invested \: amount }\green { = Rs \: 340}$
