A) 25 | B) 30 |

C) 35 | D) 40 |

Explanation:

A) Salman Rushdi | B) Deepak Nayyar |

C) Javier Moro | D) Khurshid M Kasuari |

A) 111 | B) 117 |

C) 123 | D) 139 |

Explanation:

We know that,

$\frac{\mathbf{M}\mathbf{1}\mathbf{}\mathbf{\times}\mathbf{}\mathbf{D}\mathbf{1}}{\mathbf{W}\mathbf{1}}\mathbf{}\mathbf{=}\mathbf{}\frac{\mathbf{M}\mathbf{2}\mathbf{}\mathbf{\times}\mathbf{}\mathbf{D}\mathbf{2}}{\mathbf{W}\mathbf{2}}$

Here M1 = 1, D1 = 6 min, W1 = 1 and M2 = M, D2 = 90 min, W2 = 1845

$\frac{\mathbf{1}\mathbf{}\mathbf{\times}\mathbf{}\mathbf{6}}{\mathbf{1}}\mathbf{}\mathbf{=}\mathbf{}\frac{\mathbf{M}\mathbf{}\mathbf{\times}\mathbf{}\mathbf{90}}{\mathbf{1845}}$

=> **M = 123**

If the Multiples for two or more numbers which are Common, then those Multiples are said to be **Common Multiples. **

**For Example :**

Multiples of **3** are **3, 6, 9, 12, 15, 18, 21, 24, 27, 30,...**

Multiples of **5** are **5, 10, 15, 20, 25, 30,...**

Here common multiples of 3 & 5 upto 30 are **15, 30.**

A) 0 | B) 1 |

C) Undefined | D) Indeterminate |

Explanation:

**Indeterminate are those,which mathematics can’t determine.**

Because we don’t actually know which one is the exact answer for this due to having lots of results for this.

**Explanation::**

- Let us think by this analogy that,

0 / 1 = 0

0 / 2 = 0

…………

………..

we can say **0 / n = 0** from this we can write, **0/0 = 0**

- Again, another analogy,(
**from limiting concept of 1/0 = infinity**)

1 / 0 = +*∞* or -*∞*

2 /0 = +*∞* or -*∞*

………

……….

we can say **0 / 0 = ***∞*

- Again, another analogy,

1 / 1 = 1

2/2 = 1

………..

………..

we can say, **0/0 = 1**

Now, you see it’s confusing. ** Every analog is mathematically correct then which one is the right answer for 0/0. Therefore Mathematics can’t determine this fact**.

*So, 0/0 is indeterminate*
