SRCC GBO 2015 Question Paper

The state showing the minimum percentage increase in total literacy is Bihar at 22.34%

The change in percentage population growth rate for Bihar is -0.04

The numerical ratio of the percentage increase in total literacy to the change in the percentage population growth rate is nearly 

$$\dfrac{22.34}{0.04}=558.5$$

Hence, the answer is 558.5

The ratio of the percentage increase in female literacy to the percentage increase in total literacy for

1) Kerala is $$\dfrac{31.2}{30.17}=1.0341$$

2) Maharashtra is $$\dfrac{25.92}{25.87}=1.0019$$

3) Manipur is $$\dfrac{29.68}{29.61}=1.0023$$

4) Madhya Pradesh is $$\dfrac{22.86}{25.58}=0.8936$$

Hence, the maximum is for Kerala.

The overall simple average of the percentage increase in female literacy is

$$\dfrac{23.32+19.48+26.2+28.67+31+26.63+31.2+22.86+25.92+29.68}{10}=26.496$$

The simple average of percentage increase in female literacy of those states where the percentage increase is more than the overall average is

$$\dfrac{28.67+31+26.63+31.2+29.68}{5}=29.436$$

Hence, the ratio is $$\dfrac{26.496}{29.436}=0.90$$

Hence, the answer is Option C.

The overall simple average of the percentage increase in female literacy is

$$\dfrac{23.32+19.48+26.2+28.67+31+26.63+31.2+22.86+25.92+29.68}{10}=26.496$$

The simple overall average of the percentage increase in total literacy is

$$\dfrac{25.17+22.34+27.21+29.19+31.06+27.52+30.17+25.58+25.87+29.61}{10}=27.372$$

Hence, the ratio is $$\dfrac{26.496}{27.372}=0.968$$

Hence, the answer is Option B.

The highest percentage increase in total literacy is exhibited by Himachal Pradesh at 31.06%

From the given graph, we can see that India's GDP stacked bar graph 
Services account for 20% of it. 
20% is 0.2 or 1/5

Hence, the answer is $$\frac{1}{5}th$$

20% of Sri Lanka's GDP is manufacturing. The GDP is given to be 10000 crore. 
20% of that will be 0.2(10000)=2000 crore. 

Manufacturing is 40%
Services is 20%
Miscellaneous is 10%

Total is 70%. 

GDP is given to be 30000 crore. 70% of that will be 21000 crore. 

It cannot be determined as this graph only provides the percentages of the GDP; the absolute figures are not given. Hence, even though for both the countries, services and miscellaneous together account for 30% we cannot say for certain due to the fact the absolute figures for the GDP is not given. 

Let's say that India's and Sri Lanka's GDPs are 100X. 

Sri Lanka's manufacturing will be 40X, and India's services will be 20X. 

That means Sri Lanka's manufacturing part of GDP is 100% more than India's services.
