Question

sum of money amounts to 6950 at 8% simple interest per annum and the end of 2 year find the principal​

Answer 1

Step-by-step explanation:

Let the principal be ₹100

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

$\implies$ $\sf{SI={\Large\frac{100×2×8}{100}} }$

$\implies$ $\sf{SI=16 }$

$\implies$ $\sf{A=P+SI }$

$\implies$ $\sf{A=100+16 }$

$\implies$ $\sf{A=116 }$

If, A = 116 ; P = 100

if, A = 6950 ; P = ?

By using Direct Variation :

$\implies$ $\sf{P×116=6950×100 }$

$\implies$ $\sf{P={\Large\frac{6950×100}{116}} }$

$\implies$ $\boxed{\sf{Principal=5991.37 }}$
