Directions: Anil started from city X at 10:00 AM and travelled towards city Y. After one hour, Sunil started from Y and travelled towards X. The total time taken by Anil and Sunil for their journey are (k + 2) hours and k hours respectively. They met each other at 7:00 PM.

|
Answer» LET the distance between the two cities be ‘d’ km. The distance TRAVELLED by ANIL for ONE hour = d/(k + 2) Remaining distance = d[1 – 1/(k + 2)] = d[(k + 1)/(k + 2)] km Given, ⇒ [(k + 1)/(k + 2)]/[d/(k + 2) + d/k] = 8 ⇒ k/2 = 8 ⇒ k = 16 ∴ Required number of hours taken by Anil = 16 + 2 = 18 hours |

Note: 3.84% = 1/26 of fraction.The Average Speed of train in September to February is 195 km/h and March to August is 260 km/h. Then find the ratio of the cost of travel in March to August cycle to September to February Cycle of travelling in train.1). 3 : 82). 1 : 23). 3 : 44). 1 : 7 |
|
Answer» DISTANCE travelled by TRAIN = 2600[1 - (1/26) - (1/52)] = 2450 Km Time TAKEN in MARCH to August cycle = 2450/260 Cost in March to August cycle = 2450 × 130/260 Time taken in September to February cycle = 2450/195 Cost in September to February cycle = 2450 × 78/195 ∴ Required Ratio = 5 : 4 |

So, either boxers can be in attacking mode or defensive mode at a time.Probability of a certain boxer X attacking his opponent is 100%. In his bout with Mike Tyson what is the probability that an attacking moves from boxer X encountering a defensive move from Mike Tyson?1). 0.432). 0.633). 0.734). 0.53 |
|
Answer» PROBABILITY of Mike TYSON attacking with a left jab = 0.16 Probability of Mike Tyson attacking with a right jab = 0.29 Probability of Mike Tyson attacking with a left hook = 0.12 Probability of Mike Tyson attacking with a right hook = 0.10 Probability of Mike Tyson attacking = 0.16 + 0.29 + 0.12 + 0.10 = 0.67 Probability of Mike Tyson being on defensive mode = 1 – 0.67 = 0.33 ? The Boxer X ATTACKS all the TIME, the probability of both the boxers going for an attacking mode would be totally dependent on Mike Tyson’s likeliness of going for a defensive move. ∴ The probability that an attacking moves from boxer X encountering a defensive move from Mike Tyson is equal to the probability of Mike Tyson MAKING a defensive move = 0.33 |

Direction: A, B & C together invested a total of Rs. D in the ratio 5 : 8 : 2 for X, Y and Z months respectively. Then answer as directed - Given X : Y : Z = 4 : 1 : 7, X + Y + Z = 1 year and D = 120% of the total profit earned. If A gets Rs. 300 as profit, find D.1). Rs. 7162). Rs. 7263). Rs. 7364). Rs. 746 |
|
Answer» As, profit ratio = investment ratio × time ratio ∴ Profit ratio A : B : C = (4 × 5) : (1 × 8) : (2 × 7) = 10 : 4 : 7 ∴ Total profit = (10 + 4 + 7) × 300/10 = 630 ⇒ D = 120% of P = 1.2P = 1.2 × 630 = 12 × 63 = Rs. 756 |

Note: 3.84% = 1/26 of fraction.Find the average Speed in km/h of the train for the whole journey.1). 120 km/h2). 110 km/h3). 140 km/h4). 130 km/h |
|
Answer» Distance TRAVELLED by TRAIN = 2600[1 - (1/26) - (1/52)] = 2450 Km Time TAKEN by train = 2450/196 = 12.5 Hours Additional time = 5 hours ∴ AVERAGE Speed = 2450/(12.5 + 5) = 140 km/h |
