Question

In what time will ₹2500 amount to ₹4375 at 5% annum

Answer 1

Answer:

SI=1875

T =SI×100/R×P

T=1875×100/5×2500

=15%

Answer 2

➤ Given :-

Principle :- ₹ 2500

Rate of interest :- 5%

Total amount :- ₹ 4375

➤ To Find :-

Time given for the given sum...........

➤ Formula required :-

$\dashrightarrow \tt \large \orange{ \boxed{ \tt \gray{ \dfrac{si \times 100}{p \times r} }}}$

➤ Solution :-

In the formula,

SI = Simple Interest

P = Principle

R = Rate of interest

━━━━━━━━━━━

Simple Interest :-

$\tt \longrightarrow4375 - 2500$

$\tt \longrightarrow₹1875$

Now,

Time :-

$\tt \longrightarrow \dfrac{1875 \times 100}{2500 \times 5}$

$\tt \longrightarrow \dfrac{1875 \times \cancel{100}}{ \cancel{2500} \times 5} = \dfrac{1875 \times 1}{25 \times 5}$

$\tt \longrightarrow \dfrac{ \cancel{1875} \times 1}{25 \times \cancel{5}} = \dfrac{375 \times 1}{25 \times 1}$

$\tt \longrightarrow \cancel\dfrac{375}{25} = 15$

$\Huge\therefore$The time taken in the following sum is 15 years.

$\dashrightarrow$Some related formulas :-

Simple Interest :- $\boxed{\tt P \times R \times T \div 100 }$

Rate of interest :- $\boxed{\tt SI \times 100 \div P \times T}$

Principle :- $\boxed{\tt SI \times 100 \div R \times T}$
