Answer 1

Answer:

P=800

time=18 mnths

MA=15084

E. P=Pn(n+1) /2

=800×18(18+1) /2

=400×18×19

I=EP ×R×T/100

=400×18×19×R×1/100×12

=114R

MA=Pn+I

15084=800×18+114R

15084=14400+114R

15084-14400=114R

684/114=R

R=6%

Answer 2

★Answer★

• P = ₹800 per month , n = 1 ½ years = 18 Month
• Maturity Value = ₹15084

As we know,

$\sf \green{\: Maturity \: Value,} \\ \color{green} = p \times n + \frac{Pn(n + 1)r}{2 \times 12 \times 100} \\ 15084 = 800 \times 18 + \frac{800 \times 18 \times 19 \times r}{2400} \\ 15084 - 14400 = 6 \times 19r \\ \frac{684}{6 \times 19} = r \\ \green{R = 6\% \: P.a}$
