Question 3 |

**Directions for question number 3 to 7:**

Study the following and the table and answer the questions given below. (Data of different states regarding population of states in the year 2018)

Total population of the given States = 3276000

Study the following and the table and answer the questions given below. (Data of different states regarding population of states in the year 2018)

Total population of the given States = 3276000

**Q3. If in the year 2018, population of F is increased by 10% and population of B is increased by 12% as compared to the previous year, then ______ is the ratio of population of F and B in 2017.**42 : 55 | |

62 : 55 | |

42 : 11 | |

44 : 5 |

Question 3 Explanation:

F 2018 = (15/100)*3276000

B 2018 = (20/100)*3276000

F increased by 10% in 2018.

B increases by 12% in 2018.

So, F 2017→ 1.1 times= 15*32760

B 2017→ 1.12 times = 20*32760

F 2017 : B2017 = [(15*3276)*10]/11 : [(20*32760)*100]/112

= 42:55

B 2018 = (20/100)*3276000

F increased by 10% in 2018.

B increases by 12% in 2018.

So, F 2017→ 1.1 times= 15*32760

B 2017→ 1.12 times = 20*32760

F 2017 : B2017 = [(15*3276)*10]/11 : [(20*32760)*100]/112

= 42:55

Question 4 |

**Directions for question number 3 to 7:**

Study the following and the table and answer the questions given below. (Data of different states regarding population of states in the year 2018)

Total population of the given States = 3276000

Q4. _______ is the percentage of total number of males in F, B and D together to the total population of all the given states.

Study the following and the table and answer the questions given below. (Data of different states regarding population of states in the year 2018)

Total population of the given States = 3276000

Q4. _______ is the percentage of total number of males in F, B and D together to the total population of all the given states.

24% | |

17.5% | |

28.5% | |

29.5% |

Question 4 Explanation:

Let population=X

Males of F in 2018 = (⅗)*15*(X/100) = 9X/100

Males of B in 2018 = (¾)*20*(X/100) = 15X/100

Males of D in 2018 = (⅜)*12*(X/100)=4.5X/100

Total=(28.5*X)/100

X=28.5%

Males of F in 2018 = (⅗)*15*(X/100) = 9X/100

Males of B in 2018 = (¾)*20*(X/100) = 15X/100

Males of D in 2018 = (⅜)*12*(X/100)=4.5X/100

Total=(28.5*X)/100

X=28.5%

1276040 | |

1032170 | |

1081550 | |

1161160 |

Question 7 Explanation:

Non educated people= A 2018 + B 2018

= (7/9) * (25X/100) + ⅘ * (20X / 100) * 9/9

= 1161160

= (7/9) * (25X/100) + ⅘ * (20X / 100) * 9/9

= 1161160

for every non leap year 1 odd day. and for leap year 2 odd days.

total no.of odd days = (22*1) + ( 8 * 2) = 38.

odd days = 38/7 = 3.

sunday - 3 = Thursday.

Note: Might be you did sunday + 3 = wednesday. ( here we need to calculate 30 day previous day )

for every non leap year 1 odd day. and for leap year 2 odd days.

total no.of odd days = (22*1) + ( 8 * 2) = 38.

odd days = 38/7 = 3.

Question 12 |

Select a suitable figure from the four alternatives that would complete the figure matrix.

Question 13 |

What is the value of k for which the following system of equations has no solution:

2x - 8y = 3 and kx + 4y = 10

2x - 8y = 3 and kx + 4y = 10

-2 | |

1 | |

-1 | |

2 |

Question 13 Explanation:

2X - 8Y = 3

KX + 4Y = 10

(a1 / a2) = (b1 / b2) ≠ (c1/c2)

2/K = (-8/4)

K= -1

KX + 4Y = 10

(a1 / a2) = (b1 / b2) ≠ (c1/c2)

2/K = (-8/4)

K= -1

Question 15 |

Gopal went to a fruit market with certain amount of money. With this money he can buy either 50 oranges or 40 mangoes. He retains 10% of the money for taxi fare. If he buys 20 mangoes, then the number of oranges he can buy with balance amount is:

25 | |

20 | |

18 | |

6 |

Question 15 Explanation:

50 0range = 40 Mangoes = X

Orange = X/50

Mangoes = X/40

→ X - 0.1 X - 20 M

→ X - 0.1 X - (20*(X/40))

→ 0.4 X

→ 0.4 * 50 Oranges

= 20 Oranges

Orange = X/50

Mangoes = X/40

→ X - 0.1 X - 20 M

→ X - 0.1 X - (20*(X/40))

→ 0.4 X

→ 0.4 * 50 Oranges

= 20 Oranges
