A | 208 |

B | 202 |

C | 192 |

D | 186 |

E | None of these |

Question 11 Explanation:

The pattern of the number
series is as follows—
248 – 21 = 248 – 2 = 246
246 – 22 = 246 – 4 = 242
242 – 23 = 242 – 8 = 234
234 – 24 = 234 – 16 = 218
218 – 25 = 218 – 32 = 186
∴ ? = 186

Question 12 |

C | 8 |

D | 16·25 |

E | None of these |

Question 12 Explanation:

The pattern of the number
series is as follows—
20000 ÷ 5 = 4000
4000 ÷ 4 = 1000
1000 ÷ 5 = 200
200 ÷ 4 = 50
50 ÷ 5 = 10
10 ÷ 4 = 2·5
25 ÷ 5 = 0·5
Hence, ? = 10
