To solve this problem, we can use the concept of ratios and algebraic equations.

Let's assume the weights of Mr. Gupta and Mrs. Gupta are 7x kg and 8x kg respectively. We are given that their total weight combined is 120 kg. So, we can write the equation as:

7x + 8x = 120

Combining like terms, we get:

15x = 120

Dividing both sides by 15, we get:

x = 8

So, Mr. Gupta's weight is 7x = 7 * 8 = 56 kg, and Mrs. Gupta's weight is 8x = 8 * 8 = 64 kg.

According to the given information, Mr. Gupta reduces his weight by 6 kg. So, his new weight becomes 56 - 6 = 50 kg.

The ratio between their weights changes to 5:6. Let's assume the new weight of Mrs. Gupta is y kg. So, the new ratio can be written as:

50:y = 5:6

Cross-multiplying, we get:

5y = 6 * 50

Simplifying, we get:

5y = 300

Dividing both sides by 5, we get:

y = 60

Mrs. Gupta's new weight is 60 kg.

To find the reduction in Mrs. Gupta's weight, we can subtract her new weight from her original weight:

Reduction = 64 - 60 = 4 kg

Therefore, the correct answer is option B) 4 kg.

Read the passage given below and answer the questions that follow by selecting the most appropriate option.My heart grieved when I read the other day a news item that more than two-thirds of the elderly are being ignored in their twilight years. They are isolated by their own children and are experiencing loneliness in their present lives. Most of them say they are not being respected or given good treatment by their family or society, and they are being discriminated against in their old age. Majority of the elderly attributed their loneliness to no or little interaction with family members. With fast changing socio-economic scenarios, growing nuclear families and changing value systems, the needs of the elderly have also changed. The most common problems that the elderly face are – marginalization, lack of love and affection from their loved ones, little or no access to medicines and healthcare, finding it difficult to secure their life and property. They have no work opportunities as a result of which they face financial problems. They suffer from restricted mobility and have psychological problems on account of loneliness.To improve the situation for the elderly, the Government of India may consider enacting a law like many other countries have, to make it compulsory for children to maintain and look after their parents and also establish the National Commission for Elderly Persons. At the same time, the fact remains that the real compulsion has to come out of the bonds of affection between parents and children. We would not be wrong in saying that in India the joint-family system has made a powerful contribution in cementing the bonds of affection between the old and the young.Q. The elderly do not feel ________.
