Answer:

Jiri's age is 25.

Step-by-step explanation:

Let P = Pamela's age

and J = Jiri's age. Then

                                           (1)        P = J - 12

                                           (2) P + J = 38

Substitute (1) into (2)         J - 12 + J = 38

Add 12 to each side                J + J = 50

Combine like terms                    2J = 50

Divide each side by 2                  J = 25

Jiri's age is 25.

Find the number of letters from the word MAXIMUM where two consonants cannot occur. (Permutation)​
Hunter-Best [27]

Answer:

4!

Step-by-step explanation:

In word MAXIMUM, consonants are M & X. According to the question itself, consonants should not occur together.

So, we have to put vowels at each even position; only then the condition will be satisfied.

We can put this in 3! ways (permutations of A, I & U).  

For odd positions we can put 3-M's & a X. Total ways is 4!/3!   (as repetitions of M).

Hence, the answer is 4!/3! x 3! = 24 ways.  

24=4!.
