A) (9 + 10/11) min past 2 | B) (10 + 10/11) min past 2 |

C) (11 + 10/11) min past 2 | D) (12 + 10/11) min past 2 |

Explanation:

At 2 o'clock, the hour hand is at 2 and the minute hand is at 12, i.e. they are 10 min spaces apart.

To be together, the minute hand must gain 10 minutes over the hour hand.

Now, 55 minutes are gained by it in 60 min.

10 minutes will be gained in $\frac{60}{55}\times 10$ min. = $10\frac{10}{11}$ min.

The hands will coincide at $10\frac{10}{11}$ min. past 2.

A) 22% | B) 33% |

C) 44% | D) 55% |

Explanation:

Let original length = x metres and original breadth = y metres.

Original area = xy sq.m

Increased length = $\frac{120}{100}$ and Increased breadth = $\frac{120}{100}$

New area = $\frac{120}{100}x*\frac{120}{100}y=\frac{36}{25}xy{m}^{2}$

The difference between the Original area and New area is:

$\frac{36}{25}xy-xy$

$\frac{11}{25}xy$ Increase % =$\left(\raisebox{1ex}{$\frac{11}{25}xy$}\!\left/ \!\raisebox{-1ex}{$xy$}\right.\right)*100$= 44%

A) 12.5% | B) 13.5% |

C) 11.5% | D) 14.5% |

Explanation:

Let principal = P, Then, S.I.= P and Time = 8 years

We know that S.I. = PTR/100

**Rate** = [(100 x P)/ (P x 8)]% = 12.5% per annum.

A) Snooker | B) Shooting |

C) Polo | D) Horse racing |

Explanation:

**Epsom** is a market town in Surrey, England, 22.0 km south-west of London.

Epsom Downs Racecourse holds The Derby, now a generic name for sports competitions in English-speaking countries. The town also gives its name to Epsom salts, extracted from mineral waters there.

Within the centuries-old boundaries is Epsom Downs Racecourse which features two of the five English Classic **horse races**; The Derby and The Oaks, which were first run in 1780 and 1779 respectively.

A) 196 | B) 182 |

C) 199 | D) 204 |

Explanation:

The given series follows a logic that

11 x 12, 12 x 13, 13 x 14, 14 x 15, 15 x 16,...

So the missing number is 13 x 14 = 182

A) 24min | B) 12min |

C) 13min | D) 14min |

Explanation:

In this type of problems the formuae is

(5*x+ or - t)*12/11

Here x is replaced by the first interval of given time. Here x is 5.

t is spaces apart

Case 1 : (5*x + t) * 12/11

(5*5 + 3) * 12/11

28 * 12/11 = 336/11= $31\frac{5}{11}$ min

therefore the hands will be 3 min apart at 31 5/11 min past 5.

Case 2 : (5*x - t) * 12/11

(5*5 -3 ) * 12/11

22 *12/11 = 24 min

therefore the hands will be 3 min apart at 24 min past 5

A) 360 | B) 180 |

C) 90 | D) 60 |

Explanation:

Angle traced by the hour hand in 6 hours=(360/12)*6
