    Let the duck be ‘D’

    Let the penguin be ‘P’

    Rewriting the equations in the form of D & P,

    Equation(1); D + P = 10

    Equation(2); P – D = 8

    Equation(3); 2P – 2D = ?

    From the above equations, we can conclude that equations (1) & (2), have two unknowns so they can be solved simultaneously,

    Equation(1); D + P = 10

    Can also be written as, P + D = 10

    Equation(2); P – D = 8,

    Add , equation(1) & (2),

    2P = 18

    Penguin, P = 9

    Put the value of p in equation(1),

    D + P = 10

    D + 9 = 10

    Duck, D = 1

    Now, substitute the value of both P & D in equation(3),

    2P – 2D =?

    = 2*9 – 2*1

    = 18 – 2

    =16

    2P – 2D =16

    The pattern in the given puzzle relates to the number of unique letters in each word. Here's the breakdown:

    • at: 1 unique letter (a, t)
    • cat: 1 unique letter (c, a, t) — All three letters are unique, so it counts as 1.
    • crow: 1 unique letter (c, r, o, w) — All four letters are unique, so it counts as 1.
    • brain: 2 unique letters (b, r, a, i, n) — All five letters are unique, so it counts as 2.

    Applying this pattern to house:

    • house: 3 unique letters (h, o, u, s, e) — All five letters are unique, so it counts as 3.

  • 652

    To solve the stairs math puzzle, observe the pattern in the sequence:

    • Start with the given numbers: 7, 14, 42, 168.

    Notice that each number is obtained by multiplying the previous number by an increasing factor:

    14 is 7 x 2

    42 is 14 x 3

    168 is 42 x 4

    Following this pattern, the next number should be obtained by multiplying 168 by 5:

    So, the number on top should be 840.

Find the Value of 4=?

    The answer to the sequence "1 = 4, 2 = 16, 3 = 64, 4 = ?" is 256.

    The pattern at play here is that each number in the sequence is being raised to the power of 4.

    The pattern is that each term in the sequence is obtained by multiplying the previous term by 4.

    4 raised to the power 1, equals 4x1 = 4. Therefore, 1 = 4 in this sequence.

    41 = 4

    Likewise, 4 raised to the power 2, equals 4x4 = 16. So, 2 = 16 in the sequence.

    42 =16

    Similarly, 4 raised to the power 3, equals 4x4x4 = 64. Hence, 3 = 64 in the sequence.

    43 = 64

    Therefore, to find out what 4 equals, we just need to raise it to the power 4 

    4 raised to the power 4, equals 4 x 4 x 4 x 4 = 256.

    Hence, 4 = 256 in the sequence.

    44 = 256

A father is 30 years older than his son

Que. 279

A father is 30 years older than his son. Five years ago, he was four times as old as his son. How old is the son now ?

    Let's solve this problem step by step.
    Problem:

        A father is 30 years older than his son.
        Five years ago, the father was four times as old as his son.

    We need to find the son's current age.
    Step 1: Define Variables

    Let's define the son's current age as SS years. Then the father's current age would be S+30S+30 years.
    Step 2: Set Up the Equation for 5 Years Ago

    Five years ago, the son's age was S−5S−5 years, and the father's age was (S+30)−5=S+25(S+30)−5=S+25 years.

    According to the problem, five years ago, the father was four times as old as his son:
    S+25=4×(S−5)
    Step 3: Solve the Equation

    Now, let's solve the equation:
    S+25=4(S−5)

    First, distribute the 4 on the right side:
    S+25=4S−20

    Next, get all the terms involving SS on one side by subtracting SS from both sides:
    25=3S−20

    Now, add 20 to both sides:
    45=3S

    Finally, divide by 3 to find SS:
    S=15
