let me simplify it in a simple ways.
The question is asking us to find the total no of days in X WEEKS X DAYS.

First of all, Let's take x=2 so as per the question.
We need to find the total no of days in 2 WEEKS 2 DAYS.
so here it goes:-
1 WEEK = 7DAYS so 2 WEEKS =14 DAYS (7*2) {for 3 weeks 7*3, for 4 weeks 7*4,for 5 weeks 7*5}

"7 is always common"

So 14 days + 2 days = 16 DAYS or 7 *2 days + 2 days.
or now if we will express this equation in terms of x (i,e : Instead of 2 lets use x).

So it will be 7*x+x= 8x.
If we will use 8x to find the answer of our above equation then it will be like 8*2 = 16 DAYS

Hi all, here in question it is given as x weeks x days. So everyone thinks that it as the multiplication of x weeks and x days but here we need to do the addition of x weeks and x days.

So in a week, we have 7 days then x weeks is 7x days
And given x days also in the question.

So 7x+x= 8x.

Simply we have to add the extra days given in the question to the no of weeks.

Consider the value of x=3 (assume). So we have to find for 3weeks and 3days. So the answer should be 24.

Now substitute the value of x=3 in all the options and see which one is giving the answer 24. In here only 8x gives the answer. Hence answer is 8x (8*3=24). Nothing simpler than that.

This question is incomplete without condition. This 8x formula is applicable only if a number of weeks and days are equal. If a number of weeks and days are not equal the formula will be changed to 7x + y. Hope this will help you guys.

It's a general question.

According to our calendar we have 7 days in a week.
Therefore, in 'x' weeks we have '7x' days and "x" more days are already given in question

Here is the more simple:

He is asking x weeks x days?
consider finding for x=2.

i.e; 2weeks + 2days (converting weeks in to days. i.e;1 week=7days).
= (2*7) +2
= 16 days.

Similarly
x weeks + x days
= x*7 + x
= 8x.

Consider value of x is 3.
1 week is 7 days.
So x weeks = 7*3 days & 3 days(x days).
If we convert consider 7*3 days(3week) & 3 days in 7*x days & x days which is equal 7x+x = 8x.

1 week = 7 days.
1 day = 1 day.
Then,

X week = X (7 days),
= 7X days.

X day = X (1 day),
= 1X day.

So you will get,
X week + X day = 7X + 1X,
= 8X days.

To convert weeks into days, we use to multiply the 7 * no.of weeks.

Consider.

2 weeks + 3 days.
2*7+3=17 days.

By the way.
X*7+ X = 8X.

Here x is the days.
