A) 8 | B) 4 |

C) 2 | D) -1 |

Explanation:

By the given data, we have the expression :

(3 × 15 + 19) ÷ 8 - 6 = (45 + 19) ÷ 8 - 6 = 64 ÷ 8 - 6 = 8 - 6 = 2

A) u = 1, v = 0 | B) u = 1, v = 3/2 |

C) u = 0, v = 3/4 | D) u = 0, v = 1 |

Explanation:

Using Trial and error method,

From the options u = 1, v = 3/2 satisfies both the equations.

A) 2500 | B) 2400 |

C) 2600 | D) 2300 |

Explanation:

Given (49.001)^{2} = ?

=> =~ 49 x 49

=~ 2401

=~ 2400

A) A | B) B |

C) C | D) D |

Explanation:

The quadratic equation whose roots are reciprocal of can be obtained by replacing x by 1/x.

Hence, 2 + 5(1/x) + 3 = 0

=>

A) 1 7/12 | B) 1 5/12 |

C) 3 7/12 | D) 3 1/12 |

Explanation:

? = (3 + 4 - 2 - 1) + ( 1/6 + 1/2 - 2/3 - 11/12)

= 4 + ((2+6-8-11)/12)

= 4 - 11/12 = 3 1/12.

A) 20 | B) 29 |

C) 28 | D) 24 |

Explanation:

Let the runs scored by P, Q, R, S and T be a, b, c, d and e

From given data,

a + b + c + d + e = 36 x 5 = 180

b + c = 107

Let a = x

e = x-8

d = x-3

now 3x - 11 + 107 = 180

3x = 84

x = 28

e's score = 28-8 = 20
