SRCC GBO 2015 Question Paper

At 2 months of age, both baby boys and baby girls require 1200 calories per day.

Similarly, at 8 months of age, both baby boys and baby girls require 1500 calories per day.

Hence, the answer is 2 months and 8 months.

At the age of 6 months, a baby boy requires 1700 calories and a baby girl requires 1400 calories.

So, the difference is 300 calories.

The calorie requirement per day for the four baby boys aged 4, 6, 8 and 12 months is 1400, 1700, 1500 and 3000, respectively.

Similarly, the calorie requirement per day for the three baby girls aged 2, 8 and 16 months is 1200, 1500 and 2000, respectively.

Hence, the total calorie requirement is 1400+1700+1500+3000+1200+1500+2000 = 12300

So, the answer is none of these.

In the previous question, we got the total calorie requirement as 1400+1700+1500+3000+1200+1500+2000 = 12300.

Now, if the baby girl aged 16 months is not there, there will be a reduction of the 2000 calorie requirement.

So, in percentage terms $$\dfrac{2000}{12300}\times100=16.3\%$$

Hence, the answer is 16.3%

The calorie requirement per day for the four baby boys aged 4, 6, 8 and 12 months is 1100, 1400, 1500 and 2300, respectively.

Similarly, the calorie requirement per day for the three baby girls aged 2, 8 and 16 months is 1200, 1500 and 3500, respectively.

Hence, the total calorie requirement is 1100+1400+1500+2300+1200+1500+3500 = 12500

So, the answer is none of these.

We are given in the first graph that skin is $$\dfrac{1}{10}$$, bones is $$\dfrac{1}{5}$$, muscles is $$\dfrac{3}{10}$$ and the rest is others.

The total sum must be equal to 1.

Skin + Bones + Muscles + others = 1

Others = 1 - Skin - Bones - Muscles

Others $$=\ 1\ -\ \dfrac{1}{10}\ -\ \dfrac{1}{5}\ -\ \dfrac{3}{10}\ =\ \dfrac{10\ -\ 1\ -\ 2\ -\ 3}{10}\ =\ \dfrac{4}{10}$$

Neither bones nor skin = Muscles + others = $$\ \dfrac{3}{10}\ +\ \dfrac{4}{10}\ =\ \dfrac{7}{10}\ =\ \dfrac{7}{10}\ \times\ 100\ =\ 70\%$$

Hence, the correct answer is option D.

Protein in the bones is given to be 24%, which can be written as $$\frac{24}{100}=\frac{6}{25}$$

We can say that the protein content will be proportionately distributed according to the weight of the muscles and bones. 
Muscles are 3/10 of the body weight 
Bones are 1/5 of the body weight 

The required ratio will be, $$\dfrac{\dfrac{3}{10}}{\dfrac{1}{5}}=\dfrac{3}{2}$$

It is given that Protein is $$\frac{3}{10}$$ and skin is said to be $$\frac{1}{10}$$

We are asked to find, what percentage of proteins in human body is equivalent to the weight of the skin. 
So, essentially we need to find the percentage of 0.3 that equals 0.1

$$\frac{x}{100}\left(\frac{3}{10}\right)=\frac{1}{10}$$
$$x=33.33\%$$

In the question it is told that Mr Kunal is ready to pay either of the down payments. And it is also said that he earns no interest on the income.

So, the scheme that has less installment cost will be the better option.

In case of scheme 1, he will pay monthly installments of ₹1000 per month for 2 years. That makes 12,000*2 = Rs. 24,000

In case of scheme 2, he will pay monthly installments of ₹1000 per month for 3 years. That makes 12,000*3 = Rs. 36,000

So, down payment of Rs. 25,000 is better option.

Let us calculate the total amount paid to the bike dealer for the two installment schemes.

Scheme 1: ₹25,000 down payment and monthly installments of ₹1000 per month for 2 years.

Cost incurred through this is Rs. 25,000+1000*24 = 25,000+24,000 = Rs. 49,000

Scheme 2:  ₹18,000 down payment and monthly installment of ₹1000 per month for 3 years

Cost incurred through this is Rs. 18,000+1000*36 = 18,000+36,000 = Rs. 54,000

The difference between the two is Rs. 5,000

5,000 as a percentage of 49,000 will be $$\frac{5000}{49000}\cdot100=$$ 10.2%
