Answer 1

➤ Given :-

Simple Interest :- ₹ 1200

Time :- 5 years

Rate of interest :- 12.5%

➤ To Find :-

Principle amount of the given sum

➤ Formula required :-

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

➤ Solution :-

In the formula,

SI :- Simple Interest

R :- Rate of interest

T :- Time

Now,

Principle :-

${\tt \longrightarrow \dfrac{1200 \times 100}{5 \times 12.5}}$

${\tt \longrightarrow \dfrac{1200 \times \cancel{100}}{\cancel{5} \times 12.5} = \dfrac{1200 \times 1}{1 \times 12.5}}$

${\tt \longrightarrow \cancel \dfrac{1200}{12.5} = \boxed{\tt Rs \: \: 96}}$

$\Huge\therefore$ The principle amount of the given sum is ₹ 96.
