Best answer
Correct Answer - Option 1 : 303

Given:

Total number of visitors = 1800

Number of female visitors order hotdogs = 147

Number of male visitors order hotdogs = 154

Calculation:

Let the total number of female visitors be x

⇒ Number of female visitors ordered burger = (24/100) × x

⇒ Number of female visitors ordered pizza = (28/100) × x

⇒ Number of female visitors ordered fries = (12/100) × x

⇒ Number of female visitors ordered cake = (15/100) × x

Number of female visitors order hotdog = x – {(0.24)x + (0.28)x + (0.12)x + (0.15)x} = 0.21x

⇒ 0.21x = 147

⇒ x = 14700/21 = 700

⇒ Total number of female visitors = 700

Let the total number of male visitors be y

⇒ Number of male visitors ordered burger = (14/100) × y

⇒ Number of male visitors ordered pizza = (26/100) × y

⇒ Number of male visitors ordered fries = (28/100) × y

⇒ Number of male visitors ordered cake = (18/100) × y

Number of male visitors order hotdog = y – {(0.14)y + (0.26)y + (0.28)y + (0.18)y} = 0.14y

⇒ 0.14y = 154

⇒ y = 15400/14 = 1100

⇒ Total number of male visitors = 1100

Number of male visitors order cake = (18/100) × 1100 = 198

Number of female visitors order cake = (15/100) × 700 = 105

Total number of visitors ordered cake = 198 + 105 = 303

∴ The total number of visitors who ordered the cake is 303.
