Q:

three_resistors_are_arranged_in_a_circuit_as_shown_above1559105724.PNG image

Three resistors are arranged in a circuit as shown above. The battery has an unknown but constant emf ε and a negligible internal resistance.

Now, determine the equivalent resistance of the three resistors.

A) 12 Ω B) 10 Ω
C) 16 Ω D) 15 Ω
 
Answer & Explanation Answer: A) 12 Ω

Explanation:

From the given circuit,

three_resistors_are_arranged_in_a_circuit_as_shown_above1559105964.PNG image

The resistors R1 and R2 are in parallel connection and R3 is in series with R1 & R2

The equivalent resistance of R1 and R2 is

Req = (12 × 4)/(12 + 4) = 3 Ω.

Adding R3 in series with the pair gives

R = Req + 9

R = 3 + 9

R = 12 Ω.

Q:

Solve the missing number puzzle?

missing-number-puzzle1558420078.jpg image

A) 9 B) 6
C) 5 D) 4
 
Answer & Explanation Answer: D) 4

Explanation:

Let the value to be find be 'x'.

 
Sum of individual column value = 14

 
C1 = 7 + 2 + 1 + 4 = 14
C2 = 3 + 8 + 1 + 2 = 14
C3 = 6 + 5 + 2 + 1 = 14

 

C4 = 2 + 4 + 4 + x = 14

x = 14 - 10

x = 4

 

Hence, the missing number is '4'.

Q:

Break the logic behind the given mathematical puzzle?

Maths_logic_puzzle1557901040.png image

A) 7 B) 8
C) 11 D) 13
 
Answer & Explanation Answer: B) 8

Explanation:

In the given puzzle,

The logic is in the format of lets say, a/b


In that case b doesn't matter, because

2/2 = 1,

6/5 = 6/2 = 3,

10/11 = 10/2 = 5

 

This means that equation is a/2

So 16/19 is equal 16/2 = 8.
