Answer 1

Answer:

Step-by-step explanation:

ATQ ,P=?

R=25%

T= 1.5 YEAR

Amount= 10,935 Rs

compounded Half yearly

R= 12.5

T=3 years

amount= P(1+R÷100)raised to power t

so,

10,935=p(1+125÷10)raised to power 3

Rs 10935= P (10+125)whole divided by 10 and raised to power 3

Rs 10,935=P (135÷10)or (13.5) raised to power 3

Here is your answer
Time = 1 1/2 years
= 3/2 years
so n = 3 as Compound half yearly

R = 25% p.a
= 25/2% Compounded half yearly

A = Rs 10,935

Let principal is x

As we know the formula

A = P(1+ R/100)^n
$10935 = x(1 + \frac{25}{2 \times 100} ) {}^{3} \\ \\ 10935 = x(1 + \frac{1}{8} ) {}^{3} \\ \\ 10935 = x( \frac{9}{8} ) {}^{3} \\ \\ x = \frac{10935 \times 8 \times 8 \times 8}{9 \times 9 \times 9} \\ \\ x = 7680$
Therefore Principal is Rs 7,680
