Answer 1

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 dress 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 dress + ₹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

We will have taken 49 Rs. in actuality from both of them.

• The act of combining two or more items is known as addition. The process of computing the sum of two or more numbers in mathematics is called addition. It is a fundamental mathematical procedure that is frequently used in daily life. When we work with money, figure out our food bills, or figure out the time, we frequently employ addition.
• The statement that demonstrates an addition fact is known as the addition formula and is written as addend + addend = sum.
• The process of subtracting one number from another is called subtraction. The way to calculate the difference between two numbers is by using the basic arithmetic operation of subtraction, which is represented by the symbol (-).

Here, according to the given information, it is given that,

You have borrowed 50 rs from mom and 50 rs from dad now you have rs 100.

Out of 100 you have purchased a dress of rs 97 now you have 3 rs left.'

You have returned 1 rs to mom and 1rs to dad.

This means, now we will be have 3 - 2 = 1 Re. left.

This means that, when we had taken 50 Rs. from both Mom and Dad and returned back 1 Re. to both of them, we will have taken 49 Rs. in actuality from both of them.

Hence, we will have taken 49 Rs. in actuality from both of them.
