Data Interpretation - Pie Charts

Answer: Option C

Explanation:

Number of males in U.P =		3	of (15% of N)		=	3	x	15	x N   = 9 x	N	.
		5				5		100		100

where N = 3276000.

Number of males in M.P =		3	of (20% of N)		=	3	x	20	x N   = 15 x	N	.
		4				4		100		100

Number of males in Goa =		3	of (12% of N)		=	3	x	12	x N   = 4.5 x	N	.
		8				8		100		100

Total number of males in these three states	= (9 + 15 + 4.5) x N 100
	= 28.5 x N . 100

Required Percentage =		28.5 x N 100	x 100		% = 28.5%.
		N

Answer: Option B

Explanation:

No. of illiterate people in A.P. =		7	of (25% of 3276000)		= 637000.
		9

No. of illiterate people in M.P. =		4	of (20% of 3276000)		= 524160.
		5

Total number = (637000 + 524160) = 1161160.

Answer: Option E

Explanation:

Required ratio	= 4 of (9% of 3276000) 7 3 of (8% of 3276000) 5
	= 4 x 9 7 3 x 8 5
	= 4 x 9 x 5 x 1 7 3 8
	= 15 . 14

Answer: Option B

Explanation:

Number of males in U.P.	=   3 of (15% of 3276000) 5
	= 3 x 15 x 3726000 5 100
	= 294840.

Answer: Option C

Explanation:

Let x be the population of U.P. in 1997. Then,

Population of U.P. in 1998 = 110% of x =	110	x x.
	100

Also, let y be the population of M.P. in 1997. Then,

Population of M.P. in 1998 = 112% of y =	112	x x.
	100

Ratio of populations of U.P. and M.P. in 1998 =	110 x x 100	=	110x	.
	112 x y 100		112y

From the pie-chart, this ratio is	15	.
	20

	110x	=	15		x	=	15	x	112	=	42	.
	112y		20		y		20		110		55

Thus, ratio of populations of U.P. and M.P. in 1997 = x : y = 42 : 55.
