Tao Nan School P5 SA2 2006 Math Question (Q47)


Ricci saved $200 from her salary and spent the rest. She spent 1/9 of the expenditure on a blouse, $40 on a scarf and the rest on books. The amount spent on the scarf was $20 less than that spent on the blouse. What was her salary?

Solution




She spent $20 less on the scarf than on the blouse.

Scarf cost $40, therefore blouse cost $40 + $20 = $60


(Blouse) is 1/9 of expenditure ----- $60

(Total expenditure) 9/9 ----- $60 x 9 = $540

Salary ----- $540 (total expenditure) + $200 saved = $740

Answer: Her salary was $740.
