Social Media Challenge
The answer is 20.
How did we reach that?
If Facebook = F, Google = G, Twitter = T, Pinterest = P
Follow the reasoning …….
Now our puzzle question becomes:
⇒ F + F + F = 12
⇒ G + F + T = 18
⇒ P – T = 2
⇒ G + F + P = ??
♣ 1st Equation:
3F = 12 ⇒ F = 12/3 ⇒ F = 4
♣ 2nd Equation:
G + F + T = 18 ⇒ G + 4 + T = 18 ⇒ G + T = 18 – 4 ⇒ G + T = 14
(Now, as you can see we can’t solve this further yet, but let’s try next equation)
♣ 3rd Equation:
P – T = 2
(Now compare/add this equation with the 2nd equation i.e G + T = 14)
G + T + P – T = 14 + 2 (+T and -T cancel out each other and we get)
G + P = 16
♣ 4th Equation:
G + F + P = ??
We don’t know the individual values of G & P here, but we know G + P = 16 (from 3rd equation) & F = 4 (from 1st equation), put their value in the 4th equation and you will get the answer.
(G + P) + F = ?? ⇒ 16 + 4 ⇒ 20 Answer
