Question

Find rate, if:-
1.SI=250, T=2.5 YRS, P= 12500

Answer 1

➤ Given :-

Simple Interest :- ₹ 250

Time :- 2.5 years

Principle :- ₹ 12500

➤ To Find :-

Rate of Interest of the given sum............

➤ Formula required :-

${\large\tt \dashrightarrow \orange{ \boxed{ \tt \gray{\dfrac{SI \times 100}{P \times T}}}}}$

➤ Solution :-

Rate of interest :-

${ \tt \longrightarrow \dfrac{250 \times 100}{12500 \times 2.5}}$

${ \tt \longrightarrow \dfrac{250 \times \cancel{100}}{ \cancel{12500} \times 2.5} = \dfrac{250 \times 1}{125 \times 2.5} }$

$\tt \longrightarrow \dfrac{ \cancel{250} \times 1}{125 \times \cancel{2.5}} = \dfrac{100 \times 1}{125 \times 1}$

${\tt \longrightarrow \cancel \dfrac{100}{125} = \boxed{ \tt 0.8 \bf\%}}$

$\Huge\therefore$The rate of interest in the given sum is 0.8 $\bf\%$.
