A) 64 | B) 56 |

C) 48 | D) 40 |

Explanation:

The sequence in first column is x 5. Thus, 1 x 5 = 5, 5 x 5 = 25, 25 x 5 = 125.

The sequence in third column is x 2. Thus, 7x 2 = 14, 14 x 2 = 28, 28 x 2 = 56.

The sequence in second column is x 4.

.'. Missin number = 12 x 4 = 48.

A) Default, released | B) Made, treated |

C) Maintained, sustained | D) Lost, rescued |

Explanation:

Lost, rescued are the words which gives meaning to the sentence.

For other options:

Default - Fail

Sustained - suffered are suitable and correct pairs.

A) for, because | B) for, as |

C) of, as | D) of, since |

A) 2 | B) 9 |

C) 11 | D) 12 |

Explanation:

Here in 2nd column if you add the individual digits

we get 3 + 7 + 0 =10 , 2 + 2 + 4 = 8 , 7 + 3 + 0 = 10

7 10 3 --> 7+3 =10

6 8 2 --> 6+2 =8

x 10 1 --> x+1 =10

Here we can observe that by adding 1st and 3rd column elements we get 2nd column elements

--> x = 9

A) 4 | B) 3 |

C) 2 | D) 1 |

Explanation:

Here it follows

$\frac{42}{6}-\frac{15}{3}=2$ and $\frac{38}{19}-\frac{20}{10}=0$

In the same way $\frac{39}{9}-\frac{9}{3}=1$

A) 35 | B) 34 |

C) 26 | D) 24 |

Explanation:

Here $\frac{14\times 15}{21}$= 10 and $\frac{32\times 14}{28}$ = 16

In the same way $\frac{24\times 26}{24}$= 26.

A) 14,21 | B) 21,14 |

C) 56,84 | D) 84,56 |

Explanation:

Putting A=1, B=2, C=3,..., M=13,....,X=24,Y=25, Z=26, we have :

$JR=\frac{J+R}{2}+2=\frac{10+18}{2}+2=16$

$CK=\frac{C+K}{2}+2=\frac{3+11}{2}+2=9$

$TX=\frac{T+X}{2}+2=\frac{20+24}{2}+2=24$

$OS=\frac{O+S}{2}+2=\frac{15+19}{2}+2=19$

So, the missing numbers are :

21 and 14

Hence, the answer is (b).

A) U | B) V |

C) W | D) X |

Explanation:

The letters in the first row follow the sequence +5, +7.

The letters in the second row follow the sequence +6, +8.

In the third row, the first letter G moves 7 steps forward to give the second letter N.

Clearly, the missing letter will be 9 steps ahead of N i.e. W.

A) K | B) N |

C) O | D) P |

Explanation:

The letters in the second and third rows are five steps ahead of those in the first and second trespectively.

So, the missing letter will be five steps ahead of F, which is K.
