Question 995425
 Robin shares Rs18,000 among the members of his family.
 On a pie chart, the son gets 144 degrees and his daughter received 1/3 of the amount of money that the wife received.
 How much money did the wife receive? 
:
let w = amt the wife gets
then
{{{1/3}}}w = amt the daughter gets
:
Find how much the son gets
{{{144/360}}} * 18000 = $7200
:
w + {{{1/3}}}w + 7200 = 18000
{{{4/3}}}w = 18000 - 7200
{{{4/3}}}w = 10800
multiply both sides by 3
4w = 32400
w = {{{32400/4}}}
w = $8100 for the wife
:
:
see if that adds up (daughter gets 1/3 of 8100)
7200 + 8100 + 2700 = 18000
