A) Free Charge | B) MobiWik |

C) Paytm | D) Ezetap |

A) 222 | B) 397 |

C) 404 | D) 415 |

Explanation:

The pattern of given series is :

5

14 = (5x3) - 1

45 = (14x3) + 3

130 = (45x3) - 5

(?) = (130x3) + 7

=> (?) = 397

1182 = (397x3) - 9

Thus, the missing number is 397.

A) 16 | B) 37 |

C) 81 | D) 4 |

Explanation:

The series follows the following pattern.

4

16 =

37 =

58 =

81 .

Here every number is based on the digits of previous number. Hence, **81** is the wrong number in the given series.

A) a >= b | B) a <= b |

C) a < b | D) a > b |

Explanation:

1.

5a(a-3)-3(a-3) = 0

(5a-3)(a-3) = 0

a = 3 or 3/5

2.

3b(b+2)-1(b+2) = 0

b = -2 or b = 1/3

Here when a = 3, a > b for b = -2 and b = 1/3

when a = 3/5. a > b for b = -2 and b = 1/3.

Hence it is clesr that a > b.

A) (1) | B) (2) |

C) (3) | D) (4) |

Explanation:

The error lies in part (1).

As the phrase 'as much as' needs to be replaced with 'much as I'. Tis is because we use 'as much as' for comparing two qualities or things. But here in the given sentence a contrast is given in the latter part of the sentence. So we need a conjunction like 'even though' 'although' etc...

'Much as I' also serves the same purpose.
