Detailed Solution for RRB JE ECE (CBT I) Mock Test- 2 - Question 2

OP= 37 cm and O'P = 20 cm

PQ = 24 cm

PM = MQ = 12 cm

O'M = 16 cm

OO' = 35 + 16 = 51 cm

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

### Concentrations of three solutions A, B and C, are 20%, 30% and 40%, respectively. They are mixed in the ratio 3: 5: x resulting in a solution of 30% concentration. Find x

Detailed Solution for RRB JE ECE (CBT I) Mock Test- 2 - Question 3 3 × 0.2 + 5 × 0.3 + x × 0.4 = 0.3 (3+5+x)

⇒ 2.1 + 0.4x = 0.3(8+x)

⇒ 2.1 + 0.4x = 2.4 + 0.3x

or, x = 3

RRB JE ECE (CBT I) Mock Test- 2 - Question 4

In which of the following is p > q?

I. (0.9)p > (0.9)q

II. (1.8)p < (1.8)q

III. (8.5)p > (8.5)q

IV. (1/2)p < (12)q

Detailed Solution for RRB JE ECE (CBT I) Mock Test- 2 - Question 4 Use the following results.

If (N)p > (N)q when N > 0 and positive integral

= p > q

If (N)p > (N)q when N > 0 and fractional

= p < q

If (N)P < (N)q when N > 0 and positive integral

= P < q

< If (N)p < (N)q when N > 0 and fractional

= P > q

Using these results, we get option C is the correct answer.

A shopkeeper marks the price of an article at Rs. 320. Find the cost price if, after allowing a discount of 10%, he still gains 20% on the cost price.

Detailed Solution for RRB JE ECE (CBT I) Mock Test- 2 - Question 6 Market price = 320 Rs.

Discount= 10%

Selling price = 320 x 90/100 = 288 Rs.

Profit is given = 20%

So , C.P. = [100/ (100 + Gain%)] x S.P

CP = (100/120 )x 288 = 240 Rs.

RRB JE ECE (CBT I) Mock Test- 2 - Question 7

Detailed Solution for RRB JE ECE (CBT I) Mock Test- 2 - Question 10 Let the ten's digit be x, and the unit's digit be y.

Then, number = 10x + y.

Number obtained by interchanging the digits = 10y + x.

∴ (10x + y) + (10y + x) = 11(x + y), which is divisible by 11.

RRB JE ECE (CBT I) Mock Test- 2 - Question 13

Mahesh grows potatoes in his backyard, which is in the shape of a square. Each potato takes 1 cm2 in his backyard. This year, he has been able to grow 137 more potatoes than last year. The shape of the backyard remained a square. How many potatoes did Mahesh produce this year?

Detailed Solution for RRB JE ECE (CBT I) Mock Test- 2 - Question 13 Let the area of backyard be x2 this year and previous year was y2

x2 − y2 = 137

(x+y) (x-y) = 137 x 1

x + y = 137 ---- (i)

x - y = 1 ---- (ii)

On solving eq. (i) & (ii), we get

x = 69, y = 68

No of potatoes produced this year = 692 = 4761

RRB JE ECE (CBT I) Mock Test- 2 - Question 14

The dimensions of a luggage box are 80 cm, 60 cm and 40 cm. How many sq. cm of cloth is required to cover the box?

Detailed Solution for RRB JE ECE (CBT I) Mock Test- 2 - Question 14 Surface area of a cuboid= 2(lb+bh+lh),

where l = length,

h = height of the cuboid

Let the length, breadth and height of the luggage be l , b, h respectively

Here, l = 80 cm, b = 60 cm, h = 40 cm

Therefore, area= 2(80 x 60+60 x 40+40 x 80) cm2

= 2(4800+2400+3200) cm2

= 2 x 10400 cm2

= 20800 cm2

20800sq. cm of cloth is required to cover the box

RRB JE ECE (CBT I) Mock Test- 2 - Question 15

Detailed Solution for RRB JE ECE (CBT I) Mock Test- 2 - Question 23 Let the age of A = B = y years

Age of D = y-4 years

Age of C = y+4 years

Then,

y-4+y+y+y+4 = 4 x11

y = 11

Sum of ages of the youngest and oldest boy = 7+15 = 22 years

RRB JE ECE (CBT I) Mock Test- 2 - Question 24

With 2 articles of Q, 6 pens are given free

Total price = 35 x 2 + 6 x 5 = Rs. 100

Total Price of all product = Rs 268

Discount given = 18+30 = Rs 48

Discount Percentage = 48/268×100 ≈ 18%

RRB JE ECE (CBT I) Mock Test- 2 - Question 30

The cash difference between the selling price of an article at a profit of 2% and 12% is Rs. 3. The ratio of two selling prices is:

Detailed Solution for RRB JE ECE (CBT I) Mock Test- 2 - Question 30 Let the cost price (C.P.) of the article be Rs. x.

If profit is 2%:

Selling price (S.P.) of the article = x + (2% of x) = 1.02x (∵ S.P = C.P + Profit)

If profit is 12%:

Selling price (S.P.) of the article = x + (12% of x) = 1.12x

Cash difference between the above S.P’s = Rs.3

⇒ 1.12x – 1.02x = 3

⇒ 0.1x = 3

⇒ x = 30

The ratio of two selling prices = 1.02x : 1.12x = 51 : 56

∴ The ratio of two selling prices = 51 : 56

Speed of sound is the greatest in_________.

Detailed Solution for RRB JE ECE (CBT I) Mock Test- 2 - Question 79 Sound travels faster in liquids and non-porous solids than it does in air. It travels about 4.3 times as fast in water (1,484 m/s) and nearly 15 times faster in iron (5.120 m/s) than in air at 20 degrees Celsius. Sound waves in solids are composed of compression waves (just as in gases and liquids) and exhibit a different type of sound wave called a shear wave, which occurs only in solids. The speed of sound is the distance travelled during a unit of time by a sound is the distance travelled during a unit of time by a sound wave propagating through an elastic medium. In dry air at 20°/C (68°F), the speed of sound is 343.2 meters per second (1,126 ft/s).

Nuclear reactors used to produce electricity are based on_______ .

Detailed Solution for RRB JE ECE (CBT I) Mock Test- 2 - Question 93 A nuclear reactor is a device to initiate and control a sustained nuclear chain reaction. Most commonly, they are used for generating electricity and for the propulsion of ships.

Some produce isotopes for medical and industrial use, and some are run only for research. Just as conventional power stations generate electricity by harnessing the thermal energy released from burning fossil fuels, nuclear reactors convert the thermal energy released from nuclear fission.

When a bullet is fired upward vertically, it gains _______.

Detailed Solution for RRB JE ECE (CBT I) Mock Test- 2 - Question 99 Potential energy-If a bullet is shot STRAIGHT up (90 degrees to the ground), gravity will convert nearly all of its kinetic energy to potential energy. Falling back to earth, though, does not bring it back to the same velocity. At some point, it will hit terminal velocity, slowed by air friction, and it will hit the ground at a fraction of its starting speed. In other words, all of its kinetic energy is converted to potential energy in its rise, but much of the potential energy is converted to forms of energy (heat, sound) other than velocity on its return.
