which of the following is not necessary to book a flight
a) credit card
b) arrival city
c) drivers license
d) date of travel​

Answers

It’s “ c “ a drivers license is not necessary!

The option C. Driver's License is not necessary to book a flight.

What is Driver's License?

Driver's License is an official document given to a person who is permitted to drive vehicle on the road.

This is usually given after certain tests including Physical driving and other general knowledge of driving.

Now, when we book a flight, credit card can be used to book a flight, but not necessary.

But there is a chance than you can use the credit card.

Arrival city is necessary when you book a flight because then only other procedures will follow.

Similarly, date of travel is also required in order to book the flight on a particular day.

So the least necessary document is Driver's License.

Hence Driver's License is not necessary to book a flight.

Sam's mother is twice as old as Sam. In 12 years, Sam will be as old as his mother was 12 years ago. How old are Sam and his mother now?

Answers

Answer:

Sam is 24 years old and his mother is 48 years old.

Step-by-step explanation:

Equations

Let's call

x   = Sam's current age

Since Sam's mother is twice as old as Sam:

2x = Sam's mother current age

x + 12 = Sam's age in 12 years

2x - 12 = Sam's mother age 12 years ago

These two last expressions are equal:

x + 12 = 2x - 12

Subtracting x and adding 12:

x = 24

2x = 48

Sam is 24 years old and his mother is 48 years old.

Sam, is 24 years old. His mom is 48 years old.
