Tv , Radio , Smartphone Puzzle
We know:
Tv = Smartphone (from 2nd Equation)
Tv = 3 Radio (from 4th Equation)
Therefore Tv = Smartphone = 3 Radio
Now, Lets Solve the 2nd Equation: ⇒ Camera + Radio = Tv = Smartphone ⇒ Camera + Radio = Tv
Put the “Tv = 3 Radio” value in this equation;
⇒ Camera + Radio = 3 Radio ⇒ Camera = 3 Radio – Radio ⇒ Camera = 2 Radio
Now, Solve 3rd Equation: ⇒ Camera + Smartphone = 08 + Radio Put the values;
Camera = 2 Radio, Smartphone = 3 Radio Rewrite 3rd Equation:
⇒ 2 Radio + 3 Radio = 8 + Radio ⇒ 5 Radio = 8 + Radio ⇒ 5 Radio − Radio = 8 ⇒ 4 Radio = 8 ⇒ Radio = 8/4 = 2 ⇒ Radio = 2
Now, we know;
⇒ Camera = 2 Radio, Camera = 2 (2) Camera = 4
⇒ Smartphone = 3 Radio Smartphone = 3 (2) Smartphone = 6
⇒ Smartphone = Tv = 6
Now Solve 1st Equation: ⇒ Camera + Tv + Radio = 4 Watch
⇒ 4 + 6 + 2 = 4 Watch ⇒ 12 = 4 Watch ⇒ Watch = 12/4 = 3 ⇒ Watch = 3
Solve Last Equation: ⇒ Camera + Radio × Smartphone − Watch = ??
⇒ 4 + (2 × 6) − 3 = ?? ⇒ 4 + (12) − 3 = ?? ⇒ 16 − 3 = 13
