New Pattern Data Interpretation for SBI PO, IBPS PO, IBPS RRB PO, LIC AAO and LIC ADO | DI Based on Mixture and Alligation

Directions: The table given below shows the manufacturing of five types of trucks by a company during the years 2010 to 2015. Study the table and answer the questions. 

 
Type Year
2010 2011 2012 2013 2014 2015
A 8 20 16 17 21 6
B 16 10 14 12 12 14
C 21 17 16 15 13 8
D 4 6 10 16 20 31
E 25 18 19 30 14 27

1
The percentage increase in the total manufacturing of all types of trucks in 2013 with respect to that in 2012 was:
» Explain it
B

Total manufacturing of all types of trucks in 2013

=   17+12+15+16+30

=   90


Total manufacturing of all types of trucks in 2012

=   16+14+16+10+19

=   75


Reqd. % increase 

=    90 – 75  × 100
75

=   20%


Hence, option B is correct.

2
The manufacturing of which type of trucks was 25% of total manufacturing of all types of trucks during 2014?
» Explain it
D

Total manufacturing of all types of trucks in 2014

=   21+12+13+20+14

=   80 
 

25% of 80 = 20 

 
Hence, it is clear that the manufacturing of D type of trucks in 2014 was 20.

Option D is hence the correct answer.
3
During the period 2010-15, which type of trucks shows a continuous increase in manufacturing?
» Explain it
A
By just observing the table we can find that, it is the D type of truck in which there was a continuous increase in manufacturing from 2010 to 2015.

Option A is hence the correct answer.
4
In which year was the total manufacturing of trucks of type A and B together equal to the total manufacturing of trucks of type C and D?
» Explain it
E
On calculating, we find that in none of the given years the total manufacturing of A and B is equal to the total manufacturing of C and D.

It is hence evident that the answer is option E.
 
5
In which year was manufacturing of trucks of all types taken together approximately equal to the average of the total manufacturing during the given period?
» Explain it
C

Total manufacturing of trucks of all types =

8 + 20 + 16 + 17 + 21 + 6 + 16 + 10 + 14 + 12 + 12 + 14 + 21 + 17 + 16 + 15 + 13 + 8 + 4 + 6 + 10 + 16 + 20 + 31 + 25 + 18 + 19 + 30 + 14 + 27

=   476


∴  Reqd. avg. =  476  = 79.33 ≈ 80
6


In year 2014, total manufacturing

=   21+ 12 + 13 + 20 + 14

=   80


Option C is hence the correct answer.
