The first digit of the unlock code is 6 greater than the second digit. It is also 3 times greater than the second digit . The third digit is four less than the first digit the fourth digit is the y where 8/y = 2

The four digits code is 9354.

Step-by-step explanation:

Let the code of four digits is wxzy.

Now, given that, w = x + 6 and w = 3x

Now, solving those two equations we get,

3x = x + 6

⇒ 2x = 6

⇒ x = 3

So, w = 3x = 9

Now, given that, z is four less than w.

So, z = 9 - 4 = 5

And the fourth digit i.e. y is given by,

⇒ y = 4

Therefore, the four digits code is 9354. (Answer)

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
