Question

b) 18,000 for 2 1/2 years at 10% per
annum​

Answer 1

Step-by-step explanation:

A = P (1+r/100)n

= 18000(1+10/100)²

= 18000(1+10)²

= 18000 (11)²

= 18000 × 121

= 21,78,000

Compound Interest = A - P

= 2178000 - 18000

= 2160000

Answer 2

Answer:

$\huge\bf \green{solution}$

$\bf \pink{P = rs. 18,000}$

$\bf \red{T = 2 \frac{1}{2} years = \frac{5}{2} years}$

$\bf \blue{R = 10\% \: per \: annum}$

$\bf \purple{SI \: = \frac{18000 \times 5 \times 10}{100 \times 2}}$

$\bf \orange{ = rs. \: 4500}$
