Answer 1

Answer:

120000 /4 =30000 is a ans

Answer 2

➤ Given :-

Principle :- ₹ 120000

Time :- 4 years

Rate of interest :- 1%

➤ To Find :-

Total amount of the given sum..........

➤ Formula required :-

${\large \tt \dashrightarrow \orange{\boxed{\tt \gray{\dfrac{P \times R \times T}{100} + Principle}}}}$

➤ Solution :-

First, we should find the simple interest by multiplying the principle, rate and time and then divide my 100........

Simple Interest :-

${\tt \longrightarrow \dfrac{120000 \times 4 \times 1}{100}}$

${\tt \longrightarrow \dfrac{\cancel{120000} \times 4 \times 1}{\cancel{100}} = \boxed{\tt 1200 \times 4 \times 1}}$

${\tt \longrightarrow 1200 \times 4 = \boxed{\tt Rs \: \:4800}}$

Now,

Total amount :-

${\tt \longrightarrow 120000 + 4800}$

${\tt \longrightarrow Rs \: \: 124800}$

$\Huge\therefore$ The total amount to be paid back to bank is ₹ 124800.

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

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

Time :- ${\boxed{\tt\dfrac{SI \times 100}{P \times R}}}$
