Correct Answer: 20.69
Explanation:
Number o girls enrolled in Dancing in Institute A = 150
Total number of girls enrolled in all the Hobby classes in Institute A = 250 + 325 + 150 = 725 Hence, required percentage = 150/725 x 100 = 20.69
Correct Answer: 2008
Explanation:
As per given graph, we can calculate
Number of Matriculate job-seekers :
In 2003 ? 1400 - 650 = 750
In 2004 ? 1625 - 1000 = 625
In 2006 ? 2300 - 1250 = 1050
In 2008 ? 1400 - 2200 = 1800
Hence, in 2008, number of Matriculate job-seekers was maximum.
Correct Answer: 962/3
Explanation:
Let expenditure of company B in 2005 = Rs. x; then
I1(Income) = x + 35/100 x = Rs. 27x/20
Since . expenditure of company B in 2006 = 90/100 x Rs. x = Rs. 9x/10.then
I2(Income ) = 9x/10 + 45/100 x 9x/10 = 9x/10 +81x/200 = Rs. 261x/200
Hence, required percentage = 261x/200/27x20 x 100 = 290/3 = 962/3%
Correct Answer: 57630
Explanation:
Given :- Total population in 1990 = 153922 , increase = 5337
Total population in 1991 = Total population in 1990 - increase in 1991 = 153922 - 5337 = 148585
Total number of children in 1991 = 21560
Total number of men in 1991 = 69395
? The number of women in 1991 = Total population in 1991 ? ( Total number of children in 1991 + Total number of men in 1991 )
= 148585 ? ( 21560 + 69395 ) = 57630.
Correct Answer: 96.3%
Explanation:
In 2004, 2005 and 2008, total import = 40 + 50 + 45 = Rs. 135 crores
In 2004, 2005 and 2008, total export = 35 + 40 + 55 = Rs. 130 crores
Required percentage = 130/135 x 100 = 96.3%
Correct Answer: + (12413)
Explanation:
As per given table , we can see that
Total population in 1990 = 153922 , increase in year 1991 = 5337
Total population in 1991 = Total population in 1990 - increase in year 1991 = 153922 ? 5337 = 148585
Required Increase or decrease of population in 1992 over 1991 = Total population in 1992 ? Total population in 1991
= 160998 ? 148585 = + ( 12413 )
