Banking exams such as IBPS PO, SSC, IBPS clerk, etc. will have a special focus on the data interpretation. Every year there are 3-4 questions on this topic in such exams. Caselet form is one such type where you need to comprehend with lots of data. Let’s see the different types of questions and methods to solve them accurately.
There are a lot of things that you need to keep in mind while solving data interpretation. It is important that you understand the data given and how the data is linked. Before solving the question see what you can derive from the information given to you. Caselet form is one such type where you need to comprehend with lots of data. The question given to you will be in the paragraph form rather than some table or chart. Thus it becomes important that you remember the data well. Here are a few caselet form questions for your understanding.
Q. Mr. Shyam wants to buy a watch which is priced at Rs. 40,500. The watch is also available at Rs. 20,000 down payment and the monthly installments of Rs. 1400 per month for 2 years or Rs. 16,000 down payment and a monthly installment of Rs. 1100 per month for 3 years. Mr. Shyam has with him Rs. 10,000 only. He wants to borrow the balance money of the down payment from a private firm. The terms of that private firm are:
If Rs. 5000 is borrowed for a period of 12 months, the rate of interest is 20 %. The interest will be calculated on the whole amount for the whole year itself. Thus the borrower needs to pay an amount of Rs. 500 per month for 12 months, because 5000 is the principal amount + 1000 as the interest rate.
If more than Rs. 9,000 is borrowed for 1 year, the rate of interest is 25 % and is calculated in exactly way as given above.
1. Suppose that Mr. Shyam is ready to pay either of the down payments then which of the installments schemes is the better option of the two? (Assume that Mr. Shyam will pay the installments out of his own pocket and he keeps his savings with himself and earns no interest on the same. Also assume that instead of borrowing the remaining money for the down payment, he saves the balance before the purchase.
A. 1100 for 3 years B. 1400 for 2 years
C. Either A or B D. Data insufficient
Ans: We need to compare the two downpayments given to us in the question and find out which one is better. One of the downpayment is available at 1400 for 2 years and other is given at 1100 for 3 years.
The total cost of the 1st downpayment will be: 20000 + 16800 + 16800 = Rs. 53600
The total cost of the 2nd downpayment will be: 16000 + 13200 + 13200 + 13200 = Rs. 55600
Thus the 1st downpayment will be a better option for Mr. Shyam as there is no interest claimed by Mr. Shyam. So, the correct answer is B.
2. What is the percentage difference in the total amount paid to the watch dealer, between the two installment schemes (with respect to the total payment of the scheme with Rs. 20,000 as the down payment)?
A. 3.73 % B. 3.37 %
C. 3.33 % D. 3.53 %
Ans: Here, we need to find the actual difference in percentage between the two installments given. The total cost of the 1st down payment is 20000 + 16800 + 16800 = Rs. 53600 and the total cost of the 2nd installment is 16000 + 13200 + 13200 + 13200 = Rs. 55600. Thus, the difference between the two installments is 55,600 – 53,600 = Rs. 2000. So the difference in percentage is 2000 x 100/53600 => 3.73 %. So, the correct answer is A.
Case 3 :
3. If Shyam can spare an extra of Rs. 2500 which is to be paid to the watch dealer and the money lender from his monthly earnings start from the first month itself, which scheme would Shyam choose?
A. 1200 for 2 years
B. 1400 for 2 years
C. 1100 for 3 years
D. Data insufficient
Ans: From the data given in the question, the amount that has to be taken for the second installment is Rs. 5000. So, the monthly expenses of Shyam will be Rs. 500 per month + the monthly installment of Rs. 1100 per month to the money lender. Thus, the total repayment will be of Rs. 1600. If Shyam opts for the first installment than he needs to borrow Rs. 10,000. Because of this Shyam has to pay a monthly installment of Rs. 1041.66 to the money lender. This is because for the amount more than 9000, 25 % tax is charged to the amount will 10000 + 2500 for 12 months. In addition to this, Shyam also needs to pay an extra amount of Rs. 1100 to the money lender. So, the total amount will Rs. 2141.66 per month.
The above amount is inside his limit so he will go with the above scheme. Thus, the correct answer is C.
