Answer:_______________

Find the compound interest on 4834 compounded half_ yearly for $\frac{3}{2}$ years at the rate of 6% per annum.

Answer: 5282.24

SOLUTION 1 :

Given:

P = 4834

r = 6%

n = 18 months = $\frac{18}{12}$ years = $\frac{3}{2}$ years

Amount after $\frac{3}{2}$ months = P[ $\frac{1+(1}{2(r}$ /100))]²ⁿ

= 4834[ $\frac{1+(1}{2x0.06)}$ ]^{(2x $\frac{3}{2}$ )}

= 4834[1+0.03]^{(2x $\frac{3}{2}$ )}

= 4834(1.03)³

= 4834 x 1.09

= 5282.24

Find the compound interest on 2629 compounded half_ yearly for $\frac{3}{2}$ years at the rate of 6% per annum.

Answer: 2872.78

SOLUTION 1 :

Given:

P = 2629

r = 6%

n = 18 months = $\frac{18}{12}$ years = $\frac{3}{2}$ years

Amount after $\frac{3}{2}$ months = P[ $\frac{1+(1}{2(r}$ /100))]²ⁿ

= 2629[ $\frac{1+(1}{2x0.06)}$ ]^{(2x $\frac{3}{2}$ )}

= 2629[1+0.03]^{(2x $\frac{3}{2}$ )}

= 2629(1.03)³

= 2629 x 1.09

= 2872.78

Find the compound interest on 4368 compounded half_ yearly for $\frac{3}{2}$ years at the rate of 6% per annum.

Answer: 4773.03

SOLUTION 1 :

Given:

P = 4368

r = 6%

n = 18 months = $\frac{18}{12}$ years = $\frac{3}{2}$ years

Amount after $\frac{3}{2}$ months = P[ $\frac{1+(1}{2(r}$ /100))]²ⁿ

= 4368[ $\frac{1+(1}{2x0.06)}$ ]^{(2x $\frac{3}{2}$ )}

= 4368[1+0.03]^{(2x $\frac{3}{2}$ )}

= 4368(1.03)³

= 4368 x 1.09

= 4773.03

Find the compound interest on 2481 compounded half_ yearly for $\frac{3}{2}$ years at the rate of 5% per annum.

Answer: 2671.77

SOLUTION 1 :

Given:

P = 2481

r = 5%

n = 18 months = $\frac{18}{12}$ years = $\frac{3}{2}$ years

Amount after $\frac{3}{2}$ months = P[ $\frac{1+(1}{2(r}$ /100))]²ⁿ

= 2481[ $\frac{1+(1}{2x0.05)}$ ]^{(2x $\frac{3}{2}$ )}

= 2481[1+0.025]^{(2x $\frac{3}{2}$ )}

= 2481(1.025)³

= 2481 x 1.08

= 2671.77

Find the compound interest on 1563 compounded half_ yearly for $\frac{3}{2}$ years at the rate of 6% per annum.

Answer: 1707.93

SOLUTION 1 :

Given:

P = 1563

r = 6%

n = 18 months = $\frac{18}{12}$ years = $\frac{3}{2}$ years

Amount after $\frac{3}{2}$ months = P[ $\frac{1+(1}{2(r}$ /100))]²ⁿ

= 1563[ $\frac{1+(1}{2x0.06)}$ ]^{(2x $\frac{3}{2}$ )}

= 1563[1+0.03]^{(2x $\frac{3}{2}$ )}

= 1563(1.03)³

= 1563 x 1.09

= 1707.93
