RRB JE ME (CBT I) Mock Test- 3 - Question 1

If length, breadth, and height of a cuboid is increased by a%, b%, and c% respectively, then its volume is increased by-

Detailed Solution for RRB JE ME (CBT I) Mock Test- 3 - Question 1 Let us suppose that each side of the cuboid be 100 units. Then its volume 1003 units

Now new sides of the cuboid are: (100 + a), (100 + b) and (100 + c)

Then its new volume = (100 + a)(100 + b)(100 + c)

= 1003+1002(a+b+c)+100(ab+bc+ca)+abc

Then % change in volume

= 1002(a+b+c)+100(ab+bc+ca)+abc/1003) × 100

= (a+b+c + ab+bc+ca/100 + abc/(100)2)%

RRB JE ME (CBT I) Mock Test- 3 - Question 2

Surendra started a mocktail (soft drink + soda) counter. Initially, he had 140 liters of mocktail, which had 30% soda in it. He sold 20 liters of the mocktail. Then he added an equal amount of soft drink and soda. Now the ratio of soda to soft drink became 2:3. How much soda was added later on?

Detailed Solution for RRB JE ME (CBT I) Mock Test- 3 - Question 2 Initial amount of soft drink = 100% mock tail – 30% soda = 70% soft drink

Surendra sold 20 liter mock tail, so now he has 140 - 20 = 120 liters mocktail

In this 120l mock tail, the ratio will be the same, i.e., 30% soda and 70% soft drink.

So, amount of soft drink = 70% of 120 = 84 liters

So, Amount of soda = 120 – 84 = 36 liters

Now, let Surendra add x liters of soft drink and x liters of soda

36+x/84+x = 23

108 + 3x = 168 + 2x

x = 60 liters = amount of soda added

Three-fourth part of a tank is filled with water. 50% of the water is removed from the tank and 60 liters of pure milk is added to it. If now the ratio of milk-water in the tank becomes 5:4, then the capacity of the tank will be:

Detailed Solution for RRB JE ME (CBT I) Mock Test- 3 - Question 10

As the new ratio of milk and water is 5:4

The quantity of milk = 60 liters and hence the quantity of water has to be 48 liters.

Now, 1/2 of 3/4th of the capacity of tank = 48 liters

So, capacity of the tank = 48×2×4/3 = 128 liters

The average monthly income of A and B is Rs 7760. The average monthly income of B and C is Rs. 10990 and that of C and A is Rs. 9070. What is the annual income of B?

Detailed Solution for RRB JE ME (CBT I) Mock Test- 3 - Question 18

Total income of A and B = 2 x 7760

So, A+B = 15520 ... (i)

Similarly,

B +C = 10990 x 2 = 21980... (ii)

and A+C = 9070 x 2 = 18140 ... (iii)

Adding Eqs. (i), (ii) and (iii),

2(A + B + C) = 55640

⇒ A+B + C =27820 ... (iv)

Subtracting Eq. (iii) from Eq. (iv),

B = 27820 – 18140 = 9680

Hence, annual income of B = 9680 x 12 = Rs. 116160

If a shopkeeper sells a TV at a discount of 42%, he loses 13%. At what discount should he sell the TV to earn a profit of 5%?

Detailed Solution for RRB JE ME (CBT I) Mock Test- 3 - Question 19

SP = (1−42/100) MP= (1−13/100) CP

MP = 0.87×CP/0.58= 1.5×CP

To earn profit of 5%, let the discount be D%.

New SP= (1+5/100) CP = (1−D/100) MP

1.05CP = (1−D/100) × 1.5 × CP

D= 30%

Short trick:

100 − D1/100 − D2 = 100+P1/100+P2

58/100−D2 = 87/105

⇒ D2 = 100−70 = 30%

For instant energy, athletes take:

Detailed Solution for RRB JE ME (CBT I) Mock Test- 3 - Question 75 Glucose readily mixes in the blood and gives energy, thus it is the go-to for athleteThe digestive system breaks down carbohydrates in foods and drinks into simple sugars, mainly glucose. For example, both rice and soft drink will be broken down to simple sugars in your digestive system. This simple sugar is then carried to each cell through the bloodstream.

The pancreas secretes a hormone called insulin, which helps the glucose to migrate from the blood into the cells. Once inside a cell, the glucose is ‘burned’ along with oxygen to produce energy. Our brain, muscles and nervous system all rely on glucose as their main fuel to make energy.

The body converts excess glucose from food into glycogen. Glycogen acts as a storage form of glucose within the muscle tissue and the liver. Its role is to supplement blood sugar levels if they drop between meals or during physical activity.

RRB JE ME (CBT I) Mock Test- 3 - Question 89

How many chromosomes pairs are in a human body?

Detailed Solution for RRB JE ME (CBT I) Mock Test- 3 - Question 89 In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Twenty-two of these pairs, called autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, differ between males and females

A chromosome is a deoxyribonucleic acid (DNA) molecule with part or all of the genetic material (genome) of an organism. Most eukaryotic chromosomes include packaging proteins which, aided by chaperone proteins, bind to and condense the DNA molecule to prevent it from becoming an unmanageable tangle.

Chromosomes are normally visible under a light microscope only when the cell is undergoing the metaphase of cell division (where all chromosomes are aligned in the center of the cell in their condensed form). Before this happens, every chromosome is copied once (S phase), and the copy is joined to the original by a centromere, resulting either in an X-shaped structure (pictured to the right) if the centromere is located in the middle of the chromosome or a two-arm structure if the centromere is located near one of the ends. The original chromosome and the copy are now called sister chromatids. During metaphase the X-shape structure is called a metaphase chromosome. In this highly condensed form chromosomes are easiest to distinguish and study. In animal cells, chromosomes reach their highest compaction level in anaphase during chromosome segregation.

Chromosomal recombination during meiosis and subsequent sexual reproduction play a significant role in genetic diversity. If these structures are manipulated incorrectly, through processes known as chromosomal instability and translocation, the cell may undergo mitotic catastrophe. Usually, this will make the cell initiate apoptosis leading to its own death, but sometimes mutations in the cell hamper this process and thus cause progression of cancer.
