Quantitative Aptitude (SBI-CL) Pie Chart

The following graph shows the no. of workers of different categories A, B, C, D, E, F, G and H of a factory for the two different years.

Question: 1

What is the difference between the no. of the category F for the two years and the same category for the two years?

Explanation

	1997	1998
A	10% of 1900 = 190	12.5 % of 1800 = 225
B	285	234
C	228	180
D	475	360
E	152	144
F	285	225
G	114	162
H	171	270

The difference between the no. of workers of the category F for the two years = 285 – 225 = 60
And the percentage difference (15 – 12.5) = 2.5%
We have 100% = 3600
2.5 % = (360/100 ×2.5) = 90

Question: 4

What is the total no. of increased workers for the categories in which the no. of workers has been increased?

Explanation

The no. of workers has been increased in the category A (from 190 to 225 = 35),
G (from 114 to 162 = 48) and H (from 171 to 270 = 99).
∴ Total no. of increased workers = 35 + 48 + 99 = 182.
