# Math Puzzles Questions

A) 44 | B) 45 |

C) 46 | D) 50 |

Explanation:

Number of squares in the given figure is

**16 + 9 + 19 + 1 = 45.**

A) 8 | B) 24 |

C) 16 | D) 4 |

Explanation:

There are 16 small cubes attached to the outer walls of the cuboid.

Therefore remaining inner small cubes will be the cubes having two sides green coloured.

So the required number = 24 - 16 = 8

A) 9 times | B) 10 times |

C) 1 time | D) 0 times |

Explanation:

How many times can you subtract 10 from 100, for this if we go through logically, it is only 1 time. For the first time if we subtract 10 from 100, then there will no 100 to subtract from.

Hence, it is only 1 time we can subtract 10 from 100.

A) 11 | B) 12 |

C) 10 | D) 9 |

A) 1009 | B) 991 |

C) 2000 | D) 1000 |

Explanation:

Given total number of rats = 999919

999919 = 1000000 - 81 = $\left({1000}^{2}-{9}^{2}\right)$ = (1000+9)(1000-9) = 1009 x 991.

Since there were more rats than there were cats, 991 cats killed 1009 rats each.

A) 86 | B) 98 |

C) 104 | D) 112 |

Explanation:

Here the answer is **98.**

**The logic in the given puzzle:**

2+3 = 8

3+7 = (7+2)x3 = 27

4+5 = (5+3)x4 = 32

5+8 = (8+4)x5 = 60

6+7 = (7+5)x6 = 72

Similarly,

**7+8 = (8+6)x7 = 98.**
