# Year 2020

The four-digit number divided by 2020 gives a result of 1, **. (Can not be in form 1,*0. ) Write all the options.

Correct result:

n1 =  2323
n2 =  2525
n3 =  2727
n4 =  2929
n5 =  3131
n6 =  3333
n7 =  3535
n8 =  3737
n9 =  3939

#### Solution:

$n_{1}=2323 \ \\ d_{1}=n_{1}/2020=2323/2020=\dfrac{ 23 }{ 20 }=1.15$
$n_{2}=2525 \ \\ d_{2}=n_{2}/2020=2525/2020=\dfrac{ 5 }{ 4 }=1.25$
$n_{3}=2727 \ \\ d_{3}=n_{3}/2020=2727/2020=\dfrac{ 27 }{ 20 }=1.35$
$n_{4}=2929 \ \\ d_{4}=n_{4}/2020=2929/2020=\dfrac{ 29 }{ 20 }=1.45$
$n_{5}=3131 \ \\ d_{5}=n_{5}/2020=3131/2020=\dfrac{ 31 }{ 20 }=1.55$
$n_{6}=3333 \ \\ d_{6}=n_{6}/2020=3333/2020=\dfrac{ 33 }{ 20 }=1.65$
$n_{7}=3535 \ \\ d_{7}=n_{7}/2020=3535/2020=\dfrac{ 7 }{ 4 }=1.75$
$n_{8}=3737 \ \\ d_{8}=n_{8}/2020=3737/2020=\dfrac{ 37 }{ 20 }=1.85$
$n_{9}=3939 \ \\ d_{9}=n_{9}/2020=3939/2020=\dfrac{ 39 }{ 20 }=1.95$
