Answer 1

Answer:

2.Given, maturity value =66,250, monthly installment =2,500, n=2 years =2×12=24 months

Interest =

2400

Pn(n+1)r

=

2400

255×24×25×r

=625r

Therefore, amount =(Pn+625r)

⇒66,250=(2500×24+625r)

⇒66,250=60,000+625r

⇒6250=625r

⇒r=10%

Answer 2

Step-by-step explanation:

deposit = 2500 / month

time = 2 year or 24 month

interest =66250 - 2500×24 = 6250

I = P×T(T+1)/2×1/12×R/100

6250= 2500×24(24+1)/2×1/12×R/100

6250= 2500×25×R/100

6250= 25×25×R

6250= 625×R

R = 6250/625

R= 10%
