In this math equation puzzle, Duck & penguin are given both birds are arranged in the form of linear equations, with the help of them you need to analyze and understand the equation which helps in finding the particular value of penguin & duck and will help in decode the final problem.
Find the value of '?'
Take a pause & think...
The answer of the above equation is 10.
Explaination:
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
