Kinyua spent 1/4 of his net January salary on school fees .He spent 1/4 of remainder on electricity and water bills .He spent 1/9 of what remained on transport .if he finally has 8400 calculate total January salary
Answered by bobpursley
school fees= 1/4 Jan Salary
(jan Salary-school fees)1/4= utility bills
(Jan Salary-school fees-utility bills)1/9= transport
(jan Salary-school fees - utility bills -transport=8400
Jan Salary-school fees-utlity bills-(Jan Salary-school fees-utility bills)1/9=8400
then
8/9 (jan Salary-school fees-utility bills)=8400
(jan Salary-school fees-utility bills)=9*8400/8=9*1050=9450
(jan Salary-school fees-(jan Salary-school fees)1/4) =9450
3/4( Jan Salary-school fees)=9450
3/4( Jan Salary-1/4 jan Salary)=9450
3/4*3/4 jan Salary=9450
Jan salary= 16*9450/9=16800
now check that with the original problem statement.
Answered by henry2,
1-1/4 = 3/4.
3/4-1/4 = 2/4 = 1/2.
1/2-1/9 = 9/18-2/18 = 7/18.

7x/18 = 8400
X = $21,600 = Net Jan. salary.

¼-school fees
¼- of the remainder on electricity and water bills
1/9 of the remainder on transport
4/4- ¼=¾
¾*¼=3/16spend on electricity and water bills
To get the fraction of what was used on transport
¼+3/16=7/16
16/16-7/16=9/16
1/9*9/16=1/16
7/16+1/16=8/16
8/16=8400
16/16
16/16*8400*16/8=16,800
