Question

There are 85 people in a warehouse. Some have been turned to Zombies; some are still alive. If the Ratio of Zombies - to - Living Humans is 2 : 3, How many Zombies are there?​

Answer 1

AnswEr :

• Zombies : Living Humans = 2 : 3
• Total People in Warehouse = 85
• Find the Number of Zombies.

Let the Number of Zombies be 2x and, Number of Living Humans be 3x.

• According to the Question Now :

↠ Zombies + Living Humans = Total

↠ 2x + 3x = 85

↠ 5x = 85

• Dividing both term by 5

↠ x = 17

_______________________________

• N U M B E R S :

◗ Zombies = 2x = 2(17) = 34

◗ Living Humans = 3x = 3(17) = 51

∴ Number of Zombies in warehouse is 34.

_______________________________

• V E R I F I C A T I O N :

⇒ Zombies + Living Humans = Total

⇒ 2x + 3x = 85

⇒ 2(17) + 3(17) = 85

⇒ 34 + 51 = 85

⇒ 85 = 85 ⠀⠀⠀⠀⠀⠀⠀⠀Hence, Verified!

━━━━━━━━━━━━━━━━━━━━━━━━

• S H O R T C U T ⠀T R I C K :

• Since we know that there are two zombies for every three humans and that (2 + 3) = 5.
• we can divide 85 by 5 to figure out that in total, there are 17 groups of humans and zombies.
• From there, we can then multiply 17 by 2 and 3 and get that there are 34 zombies and 51 humans respectively.
