Question

1800 becomes rupees 2178 in certain time at the rate of 10% per annum compounded annually. The time is​

Answer 1

Answer:

2 years

Step-by-step explanation:

So, Amount=P ( 1 + r/100 )t

here,

A=2178

P=1800

T?

R=10%

Amount=P ( 1 + r/100 )t

2178=1800 ( 1+10/100)t

2178=(40/100)t

121/100=( 11/10 )t

(11/10)²= ( 11/10 )t

time=2years

Answer 2

Answer:

suppose the time is x

Step-by-step explanation:

$1800( 1 + \frac{10}{100} ) ^{x} = 2178 \\ ( \frac{11}{10} ) ^{x} = \frac{2178}{1800} \\ ( \frac{11}{10} ) ^{x} = \frac{121}{100 } = ( \frac{11}{10} ) ^{2} \\ x = 2$

show the answer is 2 years

I hope that it will make my answer II a brain list answer
