Answer

Problem

A fruit seller had some strawberries. He sells 40% strawberries and still has 360 strawberries. What is the total number of strawberries he had originally?

Clue

calculation implies percentage

Divided by 100

Hint

Operator used : Percentage

Formula:

\$"Part" / "Whole" = "Percent" / 100\$

\$"Whole" = ("Part" \times 100) / "Percent"\$

Step

Let the number of strawberries he had originally be

Step

Percent of strawberries left

\$(100 - 40)% = 60 %\$

Step

Strawberries left

\$360\$

Step

Total strawberries =

\$(360 \times 100) / 60\$

Step

⇒

\$ x = (\cancel360^6 \times 100) / \cancel60^1\$

Step

⇒

\$ x = 600\$

Step

Hence, the total number of strawberries he had originally is

600
