Henry Park Pri Sch 2007 PSLE Math Prelim Q45

Terrence earns $350 less than Leslie every month. They each spend $800 every month and save the rest of their money.
a) How long does it take for Terrence to save $2100 and Leslie to save $4550?
b) What is Terrence’s monthly salary?

Solution




a) (Leslie's savings) – (Terrence’s savings) -----
$4550 - $2100 = $2450

$2150 divided by $350 (per month) ----- 7 months

Answer: It takes 7 months.

b) In 7 months, Terrence saves $2100
1 month ----- $2100 divided by 7 = $300

Terrence’s salary ----- $800 + $300 = $1100

Answer: Terence’s monthly salary is $1100.
