How to solve Missing Data Interpretation Questions

Understanding the various conditions of the Missing DI table is very important. Try to find a relation between data in missing D.I on the basis of condition. To make the chapter easy for you all, we are sharing with you important short tricks and tips to solve Missing Table Questions in DI. Here we are explaining two types of Missing D.I questions with a detailed explanation.

The first thing to keep in mind is that you don't need to have studied mathematics at a high level to perform well on questions involving data interpretation. The ability is in analyzing the facts, extrapolating them into a mathematical answer, and then maybe using that response to reach a conclusion.

Scan the information after starting with the data. What does the title say? What do the axes or the keys represent? Make a mental note of whether anything is a number, an age, or some other kind of data; but, don't spend too much time thinking about information that could be unimportant.

Reading the question on its whole will help you determine which specific data is needed (e.g. March and April, not any other months). It's not like in school where how you solved a problem is valued. An incorrect response is an incorrect response for the numerical reasoning test.

Type 1 - Missing D.I Sample Question

Direction:(1-4) Study the following table carefully and answers the following questions carefully.

Details of various items sold by Shop keeper.

Question 1:- If the shopkeeper earns 5% profit on Wheat then what percent discount is allowed by shop keeper?

(3) 18%

(4) 10%

(5) None of these

Note:- In this type of question you can approach two types

(1). Fill all blank spaces given in the table

(2). Try to approach the whole set according to the question as there are many missing terms.

Explanation:-

In this question, we have cost price and profit% on the basis of given values easily find out the discount %

Markup price of Wheat = (800*20)/100 = 160 → 800+160 = 960

5% profit means selling price is = 840

Required discount % = (960 – 840)/960 = 12.5%

Question 2:- What percentage of profit earn by the shopkeeper on oil?

(1) 15%

(2) 25%

(3) 20%

(4) 18%

(5) None of these

Explanation:- 

Here we have the cost & selling price of oil so easily can find percentage values of profit

Required profit % = (192-160)/160 = 20%

Question 3:- If the shopkeeper has allowed a 10% discount on mark price of Wheat then what is the selling price of Wheat?

(1) Rs. 875

(2) Rs. 864

(3) Rs. 892

(4) Rs. 882

(5) None of these

Explanation:-

In this question, we have cost price and markup% on the basis of given values to easily find out the selling price.

Mark price of Wheat = 960

After allowing 10% discount = (960*10)/100 = 96

Selling price of the Wheat = 960 -96 = 864

Question 4:- If the shopkeeper faces a 20% loss on Rice then what is the cost price of the Rice?

(1) Rs. 750

(2) Rs. 580

(3) Rs. 700

(4) Rs. 620

(5) None of these
