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

Read the following bar graph which represents a company's manufacturing and selling(in lakh) of product from 2002 to 2008 and answer the following questions.

Approximately what is the average number of items sold for all the years together?

Detailed Solution: Question 4

Average = (60+55+65+50+60+80+75)/7 = 445/7 = lakh

≃ 63 lakh(Appx.)

RRB JE ME (CBT I) Mock Test- 2 - Question 5

Area of the circle is equal to the area of a rectangle having a perimeter of 100 cm and length is more than the breadth by 6 cm. What is the diameter of the circle?

Detailed Solution: Question 5

Let breadth = x, then length

= (x + 6)

∴ 2(x + x + 6) = 100

⟹ 2x + 6 = 50

⟹ x = 22 cm

∴ breadth = x 22 cm & length

= 22 + 6 = 28 cm

∴ Area of circle = Area of rectangle

⟹ π r2 = 22 x 28

⟹ 7 x 2 = 14 cm

∴ Diameter = 2r = 28 cm

RRB JE ME (CBT I) Mock Test- 2 - Question 6

A, B and C can finish a work in 8 days, 10 days and 12 days respectively. They worked together and get Rs. 740. How much will each of them get?

Detailed Solution: Question 11

Given,

1 day work of A, B, & C is 1/8 , 1/10 & 1/12 respectively

therefore, Their share in money = 1/8 : 1/10 : 1/12 = 15 : 12 : 10

Sum of their share = 15 = 12 + 10 = 37

RRB JE ME (CBT I) Mock Test- 2 - Question 12

A room 8 m long, 6 m broad and 3 m height has two windows 1 1⁄2 m × 1 m and a door 2 m × 1 1⁄2 m. Find the cost of papering the walls with paper 50 cm wide at 25 paise per meter.

Detailed Solution: Question 12

Area of walls = 2(length + breadth) x height

= 2(8 + 6) x 3 = 84 m2

Area of two windows and a door

∴ Area to be covered = 84 - 6

= 78m2

Area of paper = Area to be covered = 78

⟹ (length x breadth) of paper 78

= 156 m

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

Two circles with radii R and r touch each other externally. A direct common tangent with length l is drawn to the circles. Which is true?

Detailed Solution: Question 13

Length of direct common tangent l2 = d2 – (R – r)2

Here, d = R + r

Therefore, l2 = (R + r)2 – (R – r)2 = 4Rr

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

A certain sum, invested at 4% per annum at compound interest, compounded half-yearly, amounts to Rs. 7,803 at the end of one year. Find the sum.

Detailed Solution: Question 14

Let the sum be Rs. P.

As the interest is compounded half-yearly,

∴ R = 2% T, = 2 half years

Alternatively:-

If interest is compounded half-yearly rate will be 2%

C.l. for 2 years = 4.04%

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

RRB JE ME (CBT I) Mock Test- 2 - Question 18

If cos T = 3/5 and if sin R = 8/17, where T is in the fourth quadrant and R is in the second quadrant, then cos (T-R) is equal to:

Detailed Solution: Question 18

We have

cos T = 3/5

(since T is IV quadrant)

(since R is II quadrant)

Now, cos (T-R) = cos T cos R + sin T sin R

M1D1H1 = M2D2H2

RRB JE ME (CBT I) Mock Test- 2 - Question 23

What should come in place of the question mark (?)?

(833.25 – 384.45) ÷ 24 = ?

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

The average of three numbers is 135. The largest number is 195 and the difference between the other two is 20. The smallest number is:

Detailed Solution: Question 24

According to the question,

195+ x + x + 20 = 135 x 3

⟹ 2x + 215 = 405

⟹ 2x = 405 - 215 = 190

∴ x = 190/2 = 95

= smallest number

RRB JE ME (CBT I) Mock Test- 2 - Question 25

Distance between the parallel lines 3x + 4y – 15 = 0 and 9x + 12y – 20 = 0 is

Detailed Solution: Question 25

3x + 4y - 15 = 0

Or 9x + 12y - 45 = 0 --------- (1)

and 9x + 12y - 20 = 0 --------- (2)

The distance between two parallel lines

ax + by + c1 = 0 and ax + by + C2 = 0 is

= 25/15 = 5/3 units

RRB JE ME (CBT I) Mock Test- 2 - Question 26

In a container of 56 litres the ratio of petrol to oil is 6:1. How much oil must be added to the mixture to make this ratio 2:1?

Detailed Solution: Question 26

Quantity of petrol = (6/7) x 56 = 48 Litre

Quantity of oil = (1/7) x 56 = 8 litre

Given, New Ratio = 48/8+x = 12

48 = 16 + 2x

2x = 48 – 16

2x = 32

x = 16

16 litre is to be added

RRB JE ME (CBT I) Mock Test- 2 - Question 28

If a = 12, b = 13 and c = 14, then the value of b² c² + c² a² + a² b² – a⁴ – b⁴ – c⁴ is.

Detailed Solution: Question 28

b² c² + c² a² + a² b² – a⁴ – b⁴ – c⁴

= −12(2a⁴ + 2b⁴ + 2c⁴ – 2a² b² – 2b² c² – 2c² a²)

= −12[(a² − b²)² + (b² – c²)² + (c² – a²)²]

= −12[(144 − 169)² + (169 – 196)² + (196 – 144)²]

= −12[( −25)² + (27)² + (52)²] = –2029

RRB JE ME (CBT I) Mock Test- 2 - Question 29

The midpoint of the line segment joining (3,-8) and (x + 2, -2) is (4, -5). What is the value of X?

Detailed Solution: Question 29

Midpoint of (x1, y1) and (x2, y2)

X = (x1 + x2)/2

4 = (3 + x + 2)/2

⇒ (x+5)/2 = 4 ⇒ x = 3

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

A man saves 25% of his salary. If due to price rise he increases his monthly expenses by 25% and he is able to save only Rs. 25 per month. Find his monthly salary.

Detailed Solution: Question 30

Expenses before price rise = 100-25 = 75

25% increase in expenses = 100+25

= Rs. 125

Monthly expenses

= 375/4

If saving is 25/4 then salary = 100

If saving is 25 then salary

= Rs. 400
