Question

the price of a plot increases at constant rate of 20% every year.find its expected price after 4 yrs.if the present price is 90000.​

Answer 1

Answer:

$a = p(1 + r \div 100) ^{n}$

a=total prize after 4 years

p=present prize

r%=rate

n=time(4years)

put all value -----

$a = 90000(1 + 20 \div 100) ^{4}$

$a = 90000(100 \div 100 + 20 \div 100) ^{4}$

$a = 90000(120 \div 100) ^{4}$

$a = 90000(6 \div5 ) ^{4}$

$a = 9000(6 \times 6 \times 6 \times 6 \div 5 \times 5 \times 5 \times 5)$

$a = 90000(1296 \div 625)$

$a = 90000(2.0304)$

$a = 182736$

the prize is $182736
