Q16. Study the following pie diagrams and answer the question given below.
In 1997, the total number of which of the following types of pairs of employees was approximately equal to the 19998?
(d) C and D
Number of A-type of employees in 1998=22100×48640=10700
Similarly, number of A-type of employees in 1997 = 8596, B-type = 2579, C-type = 4298, D-type = 6447, E-type = 11605 and F-type = 9455
From here, it is clear that the number of A-type employees in 1998 was approx. equal to total number of C and D-type employees in 1997 ( = 10745).
