Calculate the number of table tennis balls that can be put inside an Indigo airplane.
[Please note that I stands for Interviewer and C stands for Candidate]

C: The number of balls that can be put inside a plane would be the =volume of the plane-30% (for the seats, equipment which are a part of the airplane)/ volume of the one TT ball.

I: Let us move forward with the approach only.

C: We can consider the middle portion of the plane to be a cylinder and the dimensions can be calculated assuming the number of rows to be 30. Assuming every row has distance of 1m distance between them which makes a 30m length adding another 5m for the cockpit area, we get a total length of 35m. An average person is of the height 2m. Hence the volume=3.14*2*2*35=400m^3.

An average table tennis ball is of a radius 2.5-3cm. The volume of one ball=4/3*3.14*3*3*3=113.04cm^3 which we convert back to my^3.

Your client is a card issuer. How can they increase their revenues?
[Please note that I stands for Interviewer and C stands for Candidate]

C: For the sake of the case can I assume the operations of the client to be like maybe say ICICI bank?

I: That's correct. But's lets only focus on increasing the profitability for the card’s revenue segment.

C: Alright! Profitability can be measured in terms of Revenues and Costs. According to my knowledge of the industry, revenue of the client would mostly be from the Gross Dollar value charged from customers, transaction or interchange fee, interest charged. And the costs are the costs of issuing, acquisition cost of the client, merchant fee paid.

Please let me know if I am missing out on anything as I am not fully aware about the payments industry.

I: That's understandable. We can move forward with these heads. How can we increase the profitability from the interest revenue?

C: Interest revenue are majorly charged when a consumer makes a purchase on the credit card. We can look into the EMI section as that is major source of this kind of an income. We can increase the EMI facilities in different products.
