Question

find the amount and compound interest on 100000 rupees compouned semi-annually for 3/2 years at rate of 8% p.a​

Answer 1

Solution:

Principal= ₹1,00,000

Rate= 8%= 8×1/2= 4%

(As its semi annually so 8% is converted here to 4%)

Time= 3/2 years

_______________________________

Amount= P(1+R/100)³

1,00,000(1+4/100)³

1,00,000(104/100)³= 104/100= 52/50

1,00,000× 52/50× 52/50× 52/50

₹112486.4

Compound interest= Amount-Principal

112486.4-100000

₹12486.4
