A) 2010 | B) 2011 |

C) 2012 | D) 2013 |

Explanation:

Suppose commodity X wil cost 40 paise more than Y after Z years. Then,

(4.20 + 0.40Z) - (6.30 + 0.15Z) = 0.40

0.25Z = 0.40 + 2.10 Z=

X will cost 40 paise more than Y 10 years after 2001 . i.e in 2011

A) 404 | B) 415 |

C) 418 | D) 420 |

Explanation:

But given remaining pages after 2nd week = 100

x = 418

The total pages in the book are 418

A) 5/3 | B) 9/5 |

C) 41/4 | D) 41/12 |

A) 3.12 | B) 312 |

C) 3120 | D) None of these |

A) 5.4327 x 3.572 x5.7 | B) 5.4327 x 3.572 x0.57 |

C) 54327 x 3572 x 0.0000057 | D) None of these |
