Question

simple interest on rupees1625 in 5/2 years is rupees 325​

Answer 1

Given :-

• S.I = Rs.325

• Time = $\sf{\dfrac{5}{2}years}$

• Principal = Rs.1625

• Rate = ?

To Find :-

• Rate

Concept Used :-

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

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

Solution :-

$\mapsto\sf{R\:=\:\dfrac{325\times100}{1625\times\dfrac{5}{2}}}$

$\mapsto\sf{R\:=\:\dfrac{2\times100\times\cancel{325}}{\cancel{1625}\times\ 5}}$

$\mapsto\sf{R\:=\:\dfrac{2\times100}{25}}$

$\mapsto\sf{R\:=\:\dfrac{2\times\cancel{100}}{\cancel{25}}}$

$\mapsto\sf{R\:=\:2\times4}$

$\mapsto\sf{R\:=\:8}$%
