Question :-
$\dfrac{9x}{8}$+1 = 10
​

Answer 1

Answer:

This is a trick. Actually, you are adding numbers that you should not. Simply put, your question is just a trick and there is a deliberate mistake in it.

Let's break it down step by step.

You take ₹50 from each of your parents, which totals up to ₹100.

You then buy a ₹97 shirt and get ₹3 as change.

₹97 + ₹3 = ₹100

Now, you give ₹1 back to each parent (and keep the remaining ₹1 with yourself). So, now you owe ₹49 to each parent, i.e., ₹98 in total.

Here comes the deliberate mistake (or the trick) in the question.

You add up ₹98 with ₹1 that you had and ask where is the missing ₹1.

But, you can't add them up because you owe ₹98 to them while you have ₹1 with you.

You owe them ₹98 which includes the ₹1 (₹97 of the shirt + ₹1 that you kept = ₹98 that you have to return).

When you gave ₹2 in total to both parents, you subtracted it from ₹100. Then why are you adding that ₹1 you have to ₹98?

You owe them = ₹98

You have given them back = ₹2

This adds up to = ₹100

Let me explain it further (for better understanding).

Now, let's assume that you give that ₹1 you had to one parent. So, now you owe ₹49 to one parent and ₹48 to the other.

So, in total you owe ₹97 to them. You have already given back ₹3. Both add up to ₹100.

Voila!

Answer 2

Answer:

We have studied procedures for working with fractions in earlier grades.

ab×cd=acbd(b≠0;d≠0)

ab+cb=a+cb(b≠0)
