RRB NTPC Mock Test - 11 (English) - Question 1

### If sinθ + cosθ = √3 cos (90 - θ), then what is the value of tanθ?

Detailed Solution for RRB NTPC Mock Test - 11 (English) - Question 1

sinθ + cosθ = √3 cos (90 - θ)

sinθ + cosθ = √3 sinθ

cosθ = √3 sinθ - sinθ

cosθ = sinθ (√3 - 1)

∴ tanθ = 1/(√3 - 1) = (√3 + 1)/2

RRB NTPC Mock Test - 11 (English) - Question 2

### If the difference between the compound interest and the simple interest on a sum of money is 0.0625 times of itself in 2 years. What is the rate of interest?

Detailed Solution for RRB NTPC Mock Test - 11 (English) - Question 2

The formula for CI at annual compound interest, including principal sum, is:

Here n = 1

0.0625P = P(1 + r/100)2 - P - (P × r × 2)/100

(1 + r/100)2 - r/50 = 1.0625

r = 25%

RRB NTPC Mock Test - 11 (English) - Question 5

Miss Agna lend an amount of Rs. 20,000 divided amongst two borrowers A and B at simple interest rate of 12% and 6% per annum respectively. If the total amount of simple interest earned in 2 years be Rs. 3840, how much amount was lend to A?

Detailed Solution for RRB NTPC Mock Test - 11 (English) - Question 5

Let the amount lend to A be Rs. α = principal amount for A

Amount lend to B = Rs. (20000 – α) = principal amount for B

We know that, Simple interest = (Principal × Rate × Time)/100

Simple interest for A = (α × 12 × 2)/100 = 0.24α

Simple interest for B = [(20000 – α) × 6 × 2]/100 = 2400 – 0.12α

Total interest = simple interest for A + simple interest for B

⇒ 3840 = 0.24α + 2400 – 0.12α

⇒ 0.12α = 3840 – 2400

⇒ α = 1440/0.12 = Rs. 12,000

∴ Amount lend to A = Rs. 12,000

RRB NTPC Mock Test - 11 (English) - Question 9

A company manufactured a pair of shoes for Rs. 2000 and sold it to a dealer at a profit of 12.5%. The dealer further sold it to a customer at Rs. 2700. What is the profit percentage of the dealer?

Detailed Solution for RRB NTPC Mock Test - 11 (English) - Question 9

Original price of shoes = Rs. 2000

Profit of company = 12.5%

⇒ Price for dealer = 2000 + 12.5% of 2000 = 2000 + 1/8 × 2000 = 2000 + 250 = Rs. 2250

But, selling price of dealer = Rs. 2700

⇒ Profit earned by dealer = 2700 - 2250 = Rs. 450

∴ Profit percentage of dealer = 450/2250 × 100 = 20%

RRB NTPC Mock Test - 11 (English) - Question 12

The following equation is incorrect. Which two signs should be interchanged to correct the equation?
7 × 16 + 20 - 20 ÷ 10 = 31

Detailed Solution for RRB NTPC Mock Test - 11 (English) - Question 12

Interchanging the following signs:

1) ÷ and - → 7 × 16 + 20 ÷ 20 - 10 = 103 ≠ 31

2) × and - → 7 - 16 + 20 × 20 ÷ 10 = 31

3) + and ÷ → 7 × 16 ÷ 20 - 20 + 10 = - 4.4 ≠ 31

4) - and + → 7 × 16 - 20 + 20 ÷ 10 = 94 ≠ 31

Hence, '× and -' is the correct answer.

RRB NTPC Mock Test - 11 (English) - Question 13

What least number must be subtracted from 1936 so that the resulting number when divided by 9, 10 and 15 will leave in case the same remainder 7?

Detailed Solution for RRB NTPC Mock Test - 11 (English) - Question 13

∵ The number should be divisible by 9, 10 and 15 leaving a remainder of 7 in each case.

Thus a remainder of 7 will be also obtained when it is divided by the LCM of 9, 10 and 15.

LCM of 9, 10 and 15 = 90

Dividing 1936 by 90 we get,

Quotient = 21

Remainder = 46

The remainder should be 7

Thus least number which should be subtracted from 1936 = 46 – 7 = 39.

RRB NTPC Mock Test - 11 (English) - Question 14

Point P (-2, 5) is the midpoint of segment AB. Co-ordinates of A are (-5, y) and B are (x, 3). What is the value of x?

Detailed Solution for RRB NTPC Mock Test - 11 (English) - Question 14

We know that the coordinates of mid points of line joining (a1,b1) and (a2,b2) are (a1 + a2)/2 and (b1 + b2)/2

For x coordinate

⇒ -2 = (-5 + x)/2

⇒ -4 = -5 + x

∴ x = 5 - 4 = 1

RRB NTPC Mock Test - 11 (English) - Question 15

The roots of the equation ax2 + x + b = 0 are equal if

Detailed Solution for RRB NTPC Mock Test - 11 (English) - Question 15

The roots of a quadratic equation px2 + qx + r = 0 are equal only when q2 = 4pr

Given equation,

ax2 + x + b = 0

By comparing the above equation with px2 + qx + r = 0, we get

p = a;

q = 1

r = b

Thus putting the values in q2 = 4pr, we get

1 = 4ab

⇒ ab = 1/4

Detailed Solution for RRB NTPC Mock Test - 11 (English) - Question 17

Given: 38 C 12 B 4 A 2 C 5 A 5

Substituting the symbols:

38 + 12 × 4 ÷ 2 + 5 ÷ 5

Solution through BODMAS:

38 + 24 + 1 = 63

Hence, the correct answer is 63.

RRB NTPC Mock Test - 11 (English) - Question 18

Find the variance of the given numbers: 36, 28, 45, and 51.

Detailed Solution for RRB NTPC Mock Test - 11 (English) - Question 18

Mean is the average of the given numbers,

⇒ Mean = (36 + 28 + 45 + 51)/4 = 160/4 = 40

Variance is calculated by taking the average of the squares of the difference between each term and the mean,

⇒ Variance = [(36 - 40)2 + (28 - 40)2 + (45 - 40)2 + (51 - 40)2]/4

= [16 + 144 + 25 + 121]/4 = 306/4 = 76.5

Detailed Solution for RRB NTPC Mock Test - 11 (English) - Question 24

Expenditure/savings = 21/4 = 21x : 4x

Income = expenditure + savings

9475 = 25x

x = 379.

∴ Monthly savings = 4x = 4 × 379 = Rs. 1516

RRB NTPC Mock Test - 11 (English) - Question 25

Diameter of wheel of a cycle is 21 cm. The cyclist takes 45 minutes to reach a destination at a speed of 16.5 km/hr. How many revolutions will the wheel make during the journey?

Detailed Solution for RRB NTPC Mock Test - 11 (English) - Question 25

Perimeter of tyre can be given as = πD = (22/7) × 21

⇒ Perimeter of tyre = 66 cm = .00066 km

Distance covered by cyclist in 45 minutes or 45/60 hrs can be given as

⇒ 16.5 × (45/60)

⇒ 16.5 × 3/4

Revolution can be given as total distance covered by cycle/perimeter of tyre

∴ The total revolutions are 18750

RRB NTPC Mock Test - 11 (English) - Question 26

The average of 6 consecutive even numbers is 25. If the next even number is also considered, then what is the new average?

Detailed Solution for RRB NTPC Mock Test - 11 (English) - Question 26

Let the first integer be 2x.

Average of 6 consecutive integers: (2x + (2x + 2) + ... + (2x + 10))/6= 12x + 2(1 + 2 + ... + 5) = 12x + 30 = 25 × 6 = 150

⇒ x = 10.

Average of new numbers: (2x + (2x + 2) + ... + (2x + 12) )/ 7 = (14x + 42)/7 = 2x + 6 = 20 + 6 = 26.

RRB NTPC Mock Test - 11 (English) - Question 27

Pipe A can fill a tank in 12 hours and Pipe B can fill the tank in 18 hours. If both the pipes are opened on alternate hours and if pipe B is opened first, then in how much time (in hours) the tank will be full?

Detailed Solution for RRB NTPC Mock Test - 11 (English) - Question 27

1-hour Efficiency of pipe A: 1/12

1-hour Efficiency of pipe B: 1/18

If both opened together, work done in 2 hours: 1/18 + 1/12 = 5/36

After 14 hours, work done = 5 × 7/36 = 35/36.

Work left = 1 – 35/36 = 1/36. This work will be done by pipe B in h hours.

⇒ h/18 = 1/36

⇒ h = 1/2

Therefore, total time = 14.5 hours

RRB NTPC Mock Test - 11 (English) - Question 29

A, B and C can do a job working alone in 6, 9 and 18 days respectively. They all work together for 1 day, then A and B quit. How many days C working alone will take to complete the remainder of the job?

Detailed Solution for RRB NTPC Mock Test - 11 (English) - Question 29

A’s 1 day work = 1/6

B’s 1 day work = 1/9

C’s 1 day work = 1/18

Let C alone worked for ‘x’ days

∵ A and B worked only for one day and C worked for (x + 1) days,

⇒ A’s 1 day work + B’s 1 day work + C’s (x + 1) days’ work = 1

⇒ 1/6 + 1/9 + (x + 1)/18 = 1

⇒ (x + 1)/18 = 13/18

⇒ x + 1 = 13

⇒ x = 13 – 1 = 12

∴ C worked alone for 12 days
