Question

Phoe’s annual expenditure is 2/5 less than Chloe’s and 1/5 more than Denise. If they spent $34020 in a year altogether, find Denise’s monthly expenditure ?

Answer

    P   :  C           P  :   D

    3   :   5          6    :   5

×2|       |×2

    6  :   10

 

  P :  C :  D  :  Total

  6  : 10:  5  :  21

21 u = 34020

1u = 34020 ÷ 21

      = 1620

Denise’s mthly expenditure = 5u÷12

                                             = (5 × $1620)÷12

                                             =$675 (ans)

annual expenditure of —
Phoe : Chloe : Denise
3 : 5 : 2.5
30 : 50 : 25
30 + 50 + 25 = 105
105 units = 34020
1 unit = 324
(324 x 25)/12 = 675

Ans : $675.
