2. 254
3. 264
4. 258
5. 269

Answer 1

Correct Answer - Option 3 : 264

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 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

Snacks	Male	Female
Burger	154	168
Pizza	286	196
Fries	308	84
Cake	198	105
Hotdog	154	147

 

 

 

 

 

 

 

Number of male visitors ordered pizza = (26/100) × 1100 = 286

Number of male visitors ordered fries = (28/100) × 1100 = 308

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

Average number of male visitors ordered pizza, fries and cake = (289 + 308 + 198)/3

⇒ Average = (792/3) = 264

∴ The average number of male visitors who order pizza, fries, and cake together is 264.
