Umesh  (10 years ago)

36400=x+x(1+20/100)+x(1+20/100)^2
36400=364x/100
x=10000
x is salary of year 2003
so salary in year 2005= 10000*(1+20/100)^2
we get $ 14400

let in 2003 income=x.so in 2004 it will be (x+x*20%)=6x/5.and in 2005 it will be(6x/5+6x/5*20%)=36x/25.
x+6x/5+36x/25=36400 then x=10000.in 2004 income=12000 and in 2005 income=14400

Athena Chakraborty  (10 years ago)

if the income in 2003 is x
then we have 1.2^2x +1.2x+x=36,400
x=10,000
so 10,000*1.2^2=14,400

Let the income be Rs x. in the year 2003.
ATQ income increase 20% every year. 20% of x will the income for the year 2004 i.e Rs 6/5 x and for the year 2005 the income will be 20% of Rs 6/5 x i.e. Rs.36/25 x.
total income is Rs 36400.
so
x+6/5x+36/25x=36400
91/25x=36400.
x=10000
income in the year 2005 is 36/25x= 36*400=Rs14400.

Let her income in the year 2003 was x.
so,a.t.q.
36400=x+x(1+20%)+x(1+20%)^2
36400=364x/100
we get,
x=10000
In the year 2005 her income was
10000*(1+20%)^2
we get,
