Important for :

1

E

Total maximum marks = 100 + 120 + 150 = 370Total marks in History and English = 95 + 80 = 175

Total marks required by her to get 70% = 370 × 70% = 259

So, she needs 259 – 175 = 84 marks to score 70%.

Hence, option E is correct.

2

A

Total number of hours in a week = 24 × 7 hrsHours spend by Pirkandu = 5 × 8 hrs

Required percentage = | 5 × 8 hrs | × 100 |

24 × 7 hrs |

= 23.80%

Hence, option (A) is correct.

3

A

Let Meetu's salary = Rs xAnuj's salary = Rs 5x/ 6

According to the question,

5x/ 6 – 2000 : x – 2000 = 4 : 5

5 (5x/ 6 – 2000) = 4 (x – 2000)

25x/ 6 – 10000 = 4x – 8000

25x/ 6 – 4x = 10000 – 8000

x/ 6 = 2000

x = 12000

Anuj's salary = Rs 10000, Meetu's salary = Rs 12000

Hence, option A is correct.

4

D

After increment price of X and Y together = Rs 175.5Price before increment = | 175.5 | × 100 = Rs 150 |

117 |

Price of apple X = | 150 | × 2 = Rs 60 |

5 |

Price of apple Y = | 150 | × 3 = Rs 90 |

5 |

X's price increased by 20%, X's price = 60 × 120% = Rs 72

Y's new price = Rs.(175.5 – 72) = Rs.103.5

Y's price increased by | 103.5 – 90 | × 100 = 15% |

90 |

Hence, option D is correct.

5

C

As per the given information, two equations can be written2000 | ( | x | ) | + 2000 | ( | y | ) |
= 700 ...(i) |

100 | 100 |

2000 | ( | x | ) | + 3000 | ( | y | ) |
= 900 ...(ii) |

100 | 100 |

The equations can be simplified to

x + y = 35

and 2x + 3y = 90.

After Solving these equation, we get

x = 15%

Hence, option (C) is correct.
