A man went to the market with Rs. 200 in his pocket. He bought 2 kg apples at Rs. 50 per kg and also bought 2 dozen bananas. What is the balance amount with him after the purchase?
Which of the below information is additionally required to answer the above question?​​

Given:

The man had Rs. 200 initially

He bought 2 kg of apples at Rs. 50 per kg, so apple cost = 2 × 50 = Rs. 100

He also bought 2 dozen bananas

Amount with the man = 200

Let the cost of dozen bananas be x,

He also bought 2 kg apples

So, Purchasing amount = 100 + 2x

Until the cost of dozen bananas is not known, we cannot get the remaining amount with him from options (a), (b) and (c).

From option (d): The cost of a dozen bananas was equal to the cost of half a kg of apples.

Cost of dozen bananas = $$\frac {1}{2}$$​ × 50 = 25

Purchasing amount = 100 + 50 = Rs. 150

Remaining amount = Rs. 50

The balance amount with him after the purchase is Rs. 50

So, option d is sufficient for answer the question.

Thus, correct option is (d).
