Question

Find the amount due on 7,500 at 8% per annum for 1 year 6 months.​

Answer 1

Given:-

• Principal= 7,500
• Rate= 8%
• Time= 1 year 6 month= 1.6 year

To Find:-

• The Amount.

Solution:-

$\underline{\overline{\mid{\bold{\blue{\mathcal{simple \: interest = \frac{p \times r \times t}{100} }}\mid}}}}$

$s.i = \frac{7500 \times 8 \times 1.6}{100}$

$= > s.i = \frac{7500 \times 8 \times 16}{100 \times 10}$

$= > s.i = \frac{75 \times 8 \times 16}{10}$

$= > s.i = \frac{600 \times 16}{10}$

$= > s.i = \frac{9600}{10}$

$\therefore \: s.i = 960$

$\underline{\overline{\mid{\bold{\red{\mathcal{Amount = principal + interest}}\mid}}}}$

$= > a = 7500 + 960$

$= > a = 8460$

∴ Find the amount due on 7,500 at 8% per annum for 1 year 6 month is Rs.8460.

Answer 2

Answer:

Given:-

Principal= 7,500

Rate= 8%

Time= 1 year 6 month= 1.6 year

To Find:-

The Amount.

Solution:-

\underline{\overline{\mid{\bold{\blue{\mathcal{simple \: interest = \frac{p \times r \times t}{100} }}\mid}}}}

100

p×r×t

∣

s.i = \frac{7500 \times 8 \times 1.6}{100}s.i=

100

7500×8×1.6

= > s.i = \frac{7500 \times 8 \times 16}{100 \times 10}=>s.i=

100×10

7500×8×16

= > s.i = \frac{75 \times 8 \times 16}{10}=>s.i=

10

75×8×16

= > s.i = \frac{600 \times 16}{10}=>s.i=

10

600×16

= > s.i = \frac{9600}{10}=>s.i=

10

9600

\therefore \: s.i = 960∴s.i=960

\underline{\overline{\mid{\bold{\red{\mathcal{Amount = principal + interest}}\mid}}}}

∣Amount=principal+interest∣

= > a = 7500 + 960=>a=7500+960

= > a = 8460=>a=8460

∴ Find the amount due on 7,500 at 8% per annum for 1 year 6 month is Rs.8460.
