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 |

Explanation:

Number of decimal places in the given expression = 8

Number of decimal places in (A) = 8

Number of decimal places in (B) = 9

Number of decimal places in (C)= 7

Clearly , the expresssion in (A) is the same as the given Expression.

A) always greater than either of the original fractions | B) always less than either of the original fractions |

C) sometimes greater and sometimes less than either of the original fractions | D) remains the same |

Explanation:

We can easily Answer this by taking some values.

The question states that the two fractions, each have values between 0 and 1.

Let us say one of the fraction is 1/2 and the other fraction is 1/3 .

The product of the two fractions is 1/2 x 1/3 = 1/6 .

is lesser than both 1/2 and 1/3 .

So, the correct answer is that the product is **always less than either of the original fractions**.

A) 69 | B) 73 |

C) 96 | D) 41 |

Explanation:

0.46 = 46/100 = 23/50.

Sum of the numerator and denominator is 23 + 50 = 73

A) 3 | B) 4 |

C) 6 | D) 1 |

A) 404 | B) 415 |

C) 418 | D) 420 |

Explanation:

Let the total book be 1

Then, in the 1st week th of book is read

i.e remaining pages =

in 2nd week he read th of it

i.e

remaining pages after 2nd week =

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 |
