Q:

The concentration of glucose in three different mixtures (glucose and alcohol) is $\frac{1}{2}, \frac{3}{5} a n d \frac{4}{5}$ respectively. If 2 litres, 3 litres and 1 litre are taken from these three different vessels and mixed. What is the ratio of glucose and alcohol in the new mixture?

A) 3:2	B) 4:3
C) 2:3	D) 3:4

Answer & Explanation Answer: A) 3:2

Explanation:

Concentration of glucose are in the ratio = $\frac{1}{2} : \frac{3}{5} : \frac{4}{5}$

Quantity of glucose taken from A = 1 liter out of 2

Quantity of glucose taken from B = 3/5 x 3 = 1.5 lit

Quantity of glucose taken from C = 0.8 lit

So, total quantity of glucose taken from A,B and C = 3.6 lit

So, quantity of alcohol = (2 + 3 + 1) - 3.6 = 2.4 lit

Ratio of glucose to alcohol = 3.6/2.4 = 3:2

Q:

A single pipe of diameter x has to be replaced by six pipes of diameters 12 cm each. The pipes are used to covey some liquid in a laboratory. If the speed/flow of the liquid is maintained the same then the value of x is ?

A) 14.69 cm	B) 29.39 cm
C) 18.65 cm	D) 22.21 cm

Answer & Explanation Answer: B) 29.39 cm

Explanation:

Volume of water flowing through 1 pipe of diameter x = Volume discharged by 6 pipes of diameter 12 cms.

As speed is same, area of cross sections should be same.

Area of bigger pipe of diameter x = Total area of 6 smaller pipes of diameter 12

i.e ${πR}^{2} = 6 πR 1^{2}$

Here R = R and R1 = 12/2 = 6

$\Rightarrow R^{2} = 6 \times 6 \times 6$

R = 14.696

=> D = X = 14.696 * 2 = 29.3938 cm.
