Question

Lena’s monthly expenditure was 30% of the total of Maria’s and Nora’s monthly expenditure. Maria’s monthly expenditure was 20% of the total of Lena’s and Nora’s monthly expenditure. The difference between Lena’s and Nora’s monthly expenditure was $1682. How much was the total monthly expenditure of the three women?

Answer

  L : M+N   Total         M : L+N    Total

30 : 100                        20:100

3   :  10        13               1 : 5            6

   (× 6)                             (× 13)

18 : 60         78             13:65          78

 

L ->18u

M ->13u

N -> 78u-18u-13u

     = 47u

N-L -> 47u – 18u

        = 29u

29u = 1682

1u = 1682/29

      = 58

Total expenditure=78u

                                 =78 × $58

                                = $4524 (Ans)

Lena : Maria + Nora : Total
30 : 100 : 130
3 : 10 : 13
18 : 60 : 78

Maria : Lena + Nora : Total
20 : 100 : 120
1 : 5 : 6
13 : 65 : 78

78 – 18 – 13 = 47 (Nora)
47 – 18 = 29
29 units = 1682
1 unit = 58
78 units = 4524
