Jharkhand Police Constable (Paper-II) Mock Test - 8 - Jharkhand Police Constable MCQ

1st term = 198
2nd term = 198 - 4 = 198 - 2² = 194
3rd term = 194 - 9 = 198 - 3² = 185
4th term = 185 - 16 = 185 - 4² = 169

⇒ For next term, square of its positon is substracted from the previous term

So, missing pattern = 169 - 5² = 169 - 25 = 144.

A + B = 70%
B + C = 50%

⇒ B = 20% , A = 50% and C = 30%
Hence, A is most efficient.

For managing, A received = 5% of Rs. 7400 = Rs. 370.
Balance = Rs. (7400 - 370) = Rs. 7030.
Ratio of their investments = (6500 x 6) : (8400 x 5) : (10000 x 3)
= 39000 : 42000 : 30000
= 13 : 14 : 10
∴ B's Share

20*25/(25-20)*6/60=10.

64000 x (1.025)⁴ = 70644.025.
Interest 6644.025 Option (d). None of these is correct.

X+x+1+x+2 = 1956
3x = 1956 – 3 = 1953
X = 1953/3 = 651
X+3 = 653
23% of largest num = 23*653/100 = 150.19

9000 + 720 + 720 + 855 + 855 + 855 + 855 + 990 
+ 990 + 1080 + 1080 + 1080 + 1080
= 9000 + 720 x 2 + 855 x 4 + 990 x 2 + 1080 x 4 = 20160

Square number can never end in 2,7

Average income over 9 months = [3 x (2250 + 500) + 3 x (2150 + 500) + 3 x (5750+500)]/9 = 3883.33

Given Data:

Compound Interest Rate (r): 20% or 0.20

The sum of money is more than doubled.

Concept:

The formula for compound interest is A = P(1+r/n)^(nt), where P is the principal amount, r is the annual interest rate, n is the number of times interest is compounded per year, t is the time the money is invested for in years. When compounded annually (n=1), this simplifies to A = P(1+r)^t.

Solution:

We know that the formula for compound interest, when compounded annually, is A = P(1 + r)^t. Here, we want to find the smallest whole number for time t so that A > 2P.

Substituting A as 2P and r as 0.20 into the formula, we get, ⇒ 2 = (1 + 0.20)^t ⇒ 2 = 1.20^t

We can now try different values for t until we reach a number where 1.20^t > 2.

Using t = 1, we get 1.20¹ = 1.20 which is not greater than 2.

Using t = 2, 1.20² = 1.44 which is not greater than 2.

Using t = 3, 1.20³ = 1.728 which is not greater than 2.

Using t = 4, 1.20⁴ = 2.0736 which is greater than 2.

Therefore, the least number of complete years in which a sum of money put out at 20% compound interest will be more than doubled is 4 years.

In ideal case :
Time taken to fill the half tank by A and B = 50 / 41.66 = 6 / 5 hours
Time taken by A,B and C to fill rest half of the tank = 50 / 16.66 = 3 hours
Total time = 
In second case :
Time taken to fill 3 / 4 tank by A and B = 75 / 41.66 = 9 / 5 hours
Time taken by A,B and C to fill rest 1 / 4 tank = 25 / 16.66 = 3 / 2 hours
Total time = 9 / 5 + 3 / 2 = 3 hours 18 minutes
Therefore, difference in time = 54 minutes

The series consists of squares and cubes of consecutive natural numbers i.e. 1², 1³, 2², 2³, 3², 3³, 4², .....

So, missing term = 4³ = 64.

Remember
Now,

Again, efficiency of Ganga, Jamuna and Saraswati
     = 100 / 1 = 100%
∴ Efficiency of Ganga = 
Efficiency of Saraswati = 
Now, number of days taken by Ganga
     = 100 / 50 = 2
Number of days taken by Saraswati
     = 100 / 33.33 = 3
∴ Difference in number of days taken by Ganga and Saraswati
     = 3 - 2 = 1 day

A:B:C
=(10×7):(12×5):(15×3)
=70:60:45
=14:12:9

20 =40*(t-5) – 20*t
T = 11
11-5 = 6

 100/12 = 8.33%

Avg of 7 no= (7+1)/2 = 8/2 = 4
Avg of 9 no = (9+1)/2 = 5
5- 4 = 1
Hence increased by 1

(256)^0.16 x (256)^0.09 = (256)^{(0.16 + 0.09)}

   = (256)^0.25

   = (256)^(25/100)

   = (256)^(1/4)

   = (4⁴)^(1/4)

   = 4^4(1/4)

   = 4¹

   = 4

P = 14 x 10 – 13 x 8 = 140 –104 = 36

Assume that he had initially Rs 100.

After spending on food, money left = Rs 75

After spending 50% of Rs 75, he had Rs 37.5

Equate the man-days
For 20 km road, 20 x 20 = 400 man-days are required
∴ For 40 km road 800 man-days are required So, 800 = 40 * x
  ► ⇒ x = 20

Non-tariff trade barriers are measures other than tariffs that restrict imports or exports. Foreign exchange controls, also known as currency controls, limit the availability or convertibility of a country's currency, affecting the ability of businesses to conduct international trade.

LPG represents the three main pillars of economic reforms in India - Liberalization, Privatization, and Globalization.

The handicraft industry is characterized by high labor intensity and artistic value. It involves skilled artisans creating unique products by hand, often using traditional techniques.
