Step-by-step explanation:

Given : If Rihanna deposit 1500 rupees in the school fund at 9 p.c.p.a for 2 year.

To find : What is the total amount she will get?

Solution :  

Using simple interest formula,

Where, P is the Principal P=Rs.1500  

R is the interest rate R=9%=0.09  

T is the time T=2 year

Substitute the values,

Total amount A=P+I  

A=Rs.1500+Rs.270  

A=Rs.1770

Therefore, the amount she will get is Rs.1770.

Answer 2

➤ Given :-

Principle :- ₹ 1500

Rate of interest :- 9%

Time :- 2 years

➤ To Find :-

Total amount that Rihanna will get

➤ Formula required :-

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

➤ Solution :-

Total amount :-

${\tt \longrightarrow \bigg( \dfrac{1500 \times 9 \times 2}{100} \bigg) + 1500}$

${\tt \longrightarrow \dfrac{\cancel{1500} \times 9 \times 2}{\cancel{100}} = \boxed{\tt 15 \times 9 \times 2}}$

${\tt \longrightarrow 15 \times 18 = \boxed{\tt 270}}$

${\tt \longrightarrow 270 + 1500}$

${\tt \longrightarrow \boxed{\tt Rs \: \: 1770}}$

$\Huge\therefore$ The total amount received by Rihanna at end is ₹ 1770.
