Detailed Solution for RRB JE ME (CBT I) Mock Test- 6 - Question 1 Area = 25 km2

Side = √25 = 5 km

Perimeter = 4 × 5 = 20 km

S = D/T

Time taken in completing one round

= (Distance)/(Speed)

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

### 1% of 1% of 25% of 1000 is?

Detailed Solution for RRB JE ME (CBT I) Mock Test- 6 - Question 2 1% of 1% of 25% of 1000

Detailed Solution for RRB JE ME (CBT I) Mock Test- 6 - Question 3

RRB JE ME (CBT I) Mock Test- 6 - Question 4

A is thrice as fast as B and is therefore able to finish a work in 60 days less than B. The time in which they can do it working together is:

Detailed Solution for RRB JE ME (CBT I) Mock Test- 6 - Question 4 Let B finish the work in 3x days

∴ A will finish the work in x days

Also 3x - x = 60

x = 30 days.

∴ A's one day work = 1/30

B"s one day work = 1/90

(A+B)'s one day work = 1/30+1/90 = 4/90

∴ Time taken to Finish the work

while (A+B) working together = 90/4

= 45/2 days.

RRB JE ME (CBT I) Mock Test- 6 - Question 5

A rectangle with one side of length 12 cm is inscribed in a circle of diameter 15cm.Find the area of rectangle.

Detailed Solution for RRB JE ME (CBT I) Mock Test- 6 - Question 5

Now:OA = OC = 7.5 cm[Radius of circle]

⇒ AC = OA + OC = 7.5 + 7.5 = 15 cm

In right triangle ABC, by pythagoras theorem (AC)2 = (AB)2 + (BC)2

⇒ 152 = 122 + (BC)2

⇒ (BC)2 = 225 - 144 = 81

= BC = 9 cm

∴ Area of rectangle= AB x BC = 12 x 9 = 108 cm2

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

RRB JE ME (CBT I) Mock Test- 6 - Question 12

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

Detailed Solution for RRB JE ME (CBT I) Mock Test- 6 - Question 12

Total income of A and B = 2 x 7760

⇒ A+B = 15520 ...(i)

Similarly,

B +C = 10990 × 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 × 12 = ₹116160

RRB JE ME (CBT I) Mock Test- 6 - Question 13

Detailed Solution for RRB JE ME (CBT I) Mock Test- 6 - Question 14

Milk : Water

New ratio 5 : 4

Old ratio 3 : 4

Difference 2 : 0

Sum of old ratios = 3 + 4 = 7

∴ Milk added = 2/7 × 70 = 20 litres

RRB JE ME (CBT I) Mock Test- 6 - Question 15

Detailed Solution for RRB JE ME (CBT I) Mock Test- 6 - Question 15

RRB JE ME (CBT I) Mock Test- 6 - Question 16

In the given figure, BO and CO are the bisector of ∠CBD and ∠BCE respectively and ∠A = 40°, then ∠BOC is equal to:

Detailed Solution for RRB JE ME (CBT I) Mock Test- 6 - Question 16 ∠BOC

= 90° - 1/2 ∠A = 90° - 1/2 (40) = 70°

RRB JE ME (CBT I) Mock Test- 6 - Question 17

For which of the following value of m the equation x2 - 6x + m = 0 has equal roots?

Detailed Solution for RRB JE ME (CBT I) Mock Test- 6 - Question 17 When equation has equal roots then

b2 – 4ac = 0

∴(–6) 2 – 4 (1) (m) = 0

36 – 4m = 0

– 4m = – 36

4m = 36

m = 9

RRB JE ME (CBT I) Mock Test- 6 - Question 18

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

Detailed Solution for RRB JE ME (CBT I) Mock Test- 6 - Question 18 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

⇒ r2 = 22×28 x 22 / 7 =7×4×7

⇒ 7 × 2 = 14 cm

∴ Diameter = 2r = 28 cm

∠APR = ∠ABC (∵ PQ I I AD I I BC)

And ∵ APR = ∠AC8 (∵ PQ I I BC)

RRB JE ME (CBT I) Mock Test- 6 - Question 20

What is the difference between the simple interest on a principal of ₹600 being calculated at 4% per annum for 3 years and 3 % per annum for 3 years?

Detailed Solution for RRB JE ME (CBT I) Mock Test- 6 - Question 20 4% for 3 years (S.I.) = 12% of the amount

3% for 3 years (S.I.) = 9% of the amount

The difference between the two is 3% of amount.

3% of 600 = 3/100× 600

= ₹18

RRB JE ME (CBT I) Mock Test- 6 - Question 26

The average age of 30 students is 9 years. If the age of their teacher is included, it becomes 10 years. What is the age of the teacher?

Detailed Solution for RRB JE ME (CBT I) Mock Test- 6 - Question 26 Total number of students = 30*9 = 270

When teacher's age is included then total age = 31*10 = 310

therefore, Required answer = 310- 270 = 40 years

RRB JE ME (CBT I) Mock Test- 6 - Question 27

Two pipes can separately fill a tank in 20 hrs and 30 hrs respectively. Both the pipes are opened to fill the tank but when the tank is 1/3 full a leak develops in the tank through which 1/3 of the water supplied by both the pipes per hour leak out. What is the total time taken to fill the tank?

Detailed Solution for RRB JE ME (CBT I) Mock Test- 6 - Question 27 Time taken by the two pipes to fill the tank

∴ 1/3 of the tank if filled in 12/3 = 4 hrs.

Now, 1/3 of the supplied water leaks out

⇒ the filler pipes are only as efficient as earlier.

⇒ the work of (12 - 4 =) 8 hrs will be completed now in

∴ total time = 4 + 12 = 16 hrs.

RRB JE ME (CBT I) Mock Test- 6 - Question 28

If 3 tan θ - 4 = 0 and 180° < θ < 270° then cosec θ = _______

Detailed Solution for RRB JE ME (CBT I) Mock Test- 6 - Question 28
