# Simplification Questions

A) 35 | B) 38 |

C) 40 | D) 42 |

Explanation:

Let the number of correct answers be X.

Number of incorrect answers = (60 – X).

4x – (60 – x) = 130

=> 5x = 190

=> x = 38

A) 500 | B) 1000 |

C) 1500 | D) 2000 |

Explanation:

Let the cost of a table and that of a chair be Rs. x and Rs, y respectively.

Then, 2x + 3y = 3500 ...(i)

and 3x + 2y = 4000 .....(ii)

solving (i) and (ii) we get x = 1000, y = 500

A) 160 | B) 175 |

C) 180 | D) 195 |

Explanation:

Suppose the man works overtime for *x* hours.

Now, working hours in 4 weeks = (5 x 8 x 4) = 160.

160 x 2.40 + *x* x 3.20 = 432

=> 3.20*x* = 432 - 384 = 48

=> *x* = 15.

Hence, total hours of work = (160 + 15) = 175.

A) 52.5 | B) 62.5 |

C) 72.5 | D) 82.5 |
