A) 420 | B) 210 |

C) 70 | D) 35 |

Explanation:

Let the required number be 'p'

We know, sum of angles in a triangle are 180 deg

According to given data,

p - p/7 = 180

7p - p = 180 x 7

=> 6p = 1260

=> p = 1260/6 = 210

A) 44 | B) 22 |

C) 24 | D) 11 |

Explanation:

Let each literature text book cost be **Rs. X**

Then, cost of mathematics text book = **Rs. (X + 2)**

ATQ,

5X = 38 + 3(X + 2)

5X = 38 + 3X + 6

2X = 44

**X = 22.**

Therefore, cost of each literature text book = **Rs. X = Rs. 22.**

And that of masthematics = **X + 2 = Rs. 24.**

A) 10 | B) 5 |

C) 50 | D) 25 |

Explanation:

Let the larger number be p

Then, smaller number = 1/6 x p = p/6

Given difference between two numbers = 25

p - p/6 = 25

5p/6 = 25

5p = 150

p = 30

Then, p/6 = 30/6 = 5

Hence, **larger number = 30** and **smaller number = 5** which makes the difference = 25.

A) 15368 | B) 12652 |

C) 14562 | D) 14965 |

Explanation:

The difference between 4632 and 20000 is given by subtracting smaler number from the bigger number.

Here the bigger number is 20000

Smaller number is 4632

Now, subtracting 4632 from 20000

20000 - 4632 = 15368 and the resut is an even number.

Hence, **The difference between 4632 and 20000 is 15368 and is an even number.**

A) 3365 | B) 2160 |

C) 1854 | D) 1632 |

Explanation:

Let the number be 3p and 5p

ATQ,

8p = 2 x 48

p = 96/8

p = 12

The numbers are 36 and 60.

Hence, the product of the numbers = **36 x 60 = 2160.**

A) 0 | B) 2 |

C) 12 | D) 10 |

Explanation:

Given

1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + **1 x 0** + 1 + 1

Using BODMAS Rule,

As multiplication precedes addition, 1 x 0 = 0,

Now, 10 + 0 + 1 + 1 = 10 + 2 = 12.

Hence, **1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 x 0 + 1 + 1 = 12.**

A) 0.5 | B) -1 |

C) 1.5 | D) -0.5 |

Explanation:

In mathematics, a geometric progression, also known as a geometric sequence, is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.

Herein the given sequence, **4, 2, 1, 0.5, 0.25, 0.125,...**

**Common Ratio r = **2/4 = 1/2 = 0.5/1 = 0.25/0.5 = 0.125/0.25 **== 0.5.**

A) 6 | B) 60 |

C) 64 | D) 10 |

Explanation:

We know that,

● Each digit has a fixed position called its place.

● Each digit has a value depending on its place called the place value of the digit.

● The face value of a digit for any place in the given number is the value of the digit itself

● Place value of a digit = (face value of the digit) × (value of the place).

Hence, the place value of 6 in 64 = **6 x 10 = 60.**

A) 91 | B) 71 |

C) 41 | D) 31 |

Explanation:

**Prime Numbers ::** Numbers which are divisible by only 1 and itself are Prime Numbers.

It's answer will be 91.

Because 91 can be divisible by 7,13,91,1.

It is quite clear that prime number should be divisible only by itself and by 1.
