Quiz 3

Kevin is 4 times as old as Daniel and is also 6 years older than Daniel.

How old is Kevin?

8

Step-by-step explanation:

Let the age of Daniel be X and Kelvin be Y

Now, According to the question,

Y = 4*X ... equation I

Also, Y = X+6 ... equation II

Finally, Equating both equations, we get

X+6 = 4X

or, 6=3X

or, X=2

Now Y = 4*X

= 4*2

= 8

Kevin would be 24 because 4 times 6 equal to 24
