Two Pipes A And B Can Fill A Tank In 20 And 30 Minutes Respectively. If Both The Pipes Are Used Together, Then How Long It Will Take To Fill The Tank ? |
|
Answer» we first GET the FILLING in 1 minute for both pipes then we will add them to get the RESULT, as PART filled by A in 1 MIN = 1/20 Part filled by B in 1 min = 1/30 Part filled by (A+B) in 1 min = 1/20 + 1/30= 1/12 So both pipes can fill the tank in 12 mins. we first get the filling in 1 minute for both pipes then we will add them to get the result, as Part filled by A in 1 min = 1/20 Part filled by B in 1 min = 1/30 Part filled by (A+B) in 1 min = 1/20 + 1/30= 1/12 So both pipes can fill the tank in 12 mins. |

The Greatest Number Which On Dividing 1657 And 2037 Leaves Remainders 6 And 5 Respectively, Is: |
|
Answer» REQUIRED NUMBER = H.C.F. of (1657 - 6) and (2037 - 5) = H.C.F. of 1651 and 2032 = 127. Required number = H.C.F. of (1657 - 6) and (2037 - 5) = H.C.F. of 1651 and 2032 = 127. |

The Average Of Runs Of A Cricket Player Of 10 Innings Was 32. How Many Runs Must He Make In His Next Innings So As To Increase His Average Of Runs By 4? |
|
Answer» Average = total runs / no.of innings = 32 So, total = Average x no.of innings = 32 x 10 = 320. Now INCREASE in avg = 4runs. So, new avg = 32+4 = 36runs Total runs = new avg x new no. of innings = 36 x 11 = 396 Runs made in the 11th inning = 396 - 320 = 76 Average = total runs / no.of innings = 32 So, total = Average x no.of innings = 32 x 10 = 320. Now increase in avg = 4runs. So, new avg = 32+4 = 36runs Total runs = new avg x new no. of innings = 36 x 11 = 396 Runs made in the 11th inning = 396 - 320 = 76 |

The Ratio Between The Length And The Breadth Of A Rectangular Park Is 3: 2. If A Man Cycling Along The Boundary Of The Park At The Speed Of 12 Km/hr Completes One Round In 8 Minutes, Then The Area Of The Park (in Sq. M) Is: |
|
Answer» Perimeter = Distance covered in 8 MIN. =12000x 8m = 1600 m. Let length = 3x METRES and breadth = 2X metres. Then, 2(3x + 2x) = 1600 or x = 160. Length = 480 m and Breadth = 320 m. Area = (480 x 320) m2 = 153600 m2. Perimeter = Distance covered in 8 min. =12000x 8m = 1600 m. Let length = 3x metres and breadth = 2x metres. Then, 2(3x + 2x) = 1600 or x = 160. Length = 480 m and Breadth = 320 m. Area = (480 x 320) m2 = 153600 m2. |

Sam And Joan Are Playing A Tennis Match. If The Probability Of Sam's Win Is 0.59, Then Find The Probability Of Joan's Win. |
|
Answer» <P>LET event A = Sam wins and event B = JOAN wins. Then, P(A) = 0.59 Since if Sam wins, Joan cannot win and if Joan wins, Sam cannot win, so we can SAY that the events A and B are mutually exclusive. Other than these two events, there are no any other possible outcomes. So, P(A)+P(B) = 1 0.59+P(B) = 1 P(B) = 1-0.59 = 0.41 Let event A = Sam wins and event B = Joan wins. Then, P(A) = 0.59 Since if Sam wins, Joan cannot win and if Joan wins, Sam cannot win, so we can say that the events A and B are mutually exclusive. Other than these two events, there are no any other possible outcomes. So, P(A)+P(B) = 1 0.59+P(B) = 1 P(B) = 1-0.59 = 0.41 |

A Mixture Contains Alcohol And Water In The Ratio 4 : 3. If 5 Liters Of Water Is Added To The Mixture, The Ratio Becomes 4: 5. Find The Quantity Of Alcohol In The Given Mixture. |
|
Answer» Let the quantity of ALCOHOL and water be 4X litres and 3x litres respectively 4x/(3x+5) = 4/5 20x = 4(3x+5) 8X = 20 x = 2.5 Quantity of alcohol = (4 x 2.5) litres = 10 litres. Let the quantity of alcohol and water be 4x litres and 3x litres respectively 4x/(3x+5) = 4/5 20x = 4(3x+5) 8x = 20 x = 2.5 Quantity of alcohol = (4 x 2.5) litres = 10 litres. |

Worker A Takes 8 Hours To Do A Job. Worker B Takes 10 Hours To Do A Job. How Long Should It Take Both A And B, Working Together To Do The Same Job ? |
|
Answer» FIRST we need to calculate 1 HOURS work, then their COLLECTIVE work as A's 1-hour work is 1/8 B's 1-hour work is 1/10 (A+B)'s 1 hour work = 1/8 + 1/10= 9/40 So both will finish the work in 40/9 hours=4 4/9 first we need to calculate 1 hours work, then their collective work as A's 1-hour work is 1/8 B's 1-hour work is 1/10 (A+B)'s 1 hour work = 1/8 + 1/10= 9/40 So both will finish the work in 40/9 hours=4 4/9 |

The Product Of Two Numbers Is 4107. If The H.c.f. Of These Numbers Is 37, Then The Greater Number Is: |
|
Answer» Let the numbers be 37a and 37b. Then, 37a x 37b = 4107 AB = 3. Now, co-primes with PRODUCT 3 are (1, 3). So, the REQUIRED numbers are (37 x 1, 37 x 3) i.e., (37, 111). Greater number = 111. Let the numbers be 37a and 37b. Then, 37a x 37b = 4107 ab = 3. Now, co-primes with product 3 are (1, 3). So, the required numbers are (37 x 1, 37 x 3) i.e., (37, 111). Greater number = 111. |

The Greatest Number Of Four Digits Which Is Divisible By 15, 25, 40 And 75 Is: |
|
Answer» GREATEST NUMBER of 4-digits is 9999. L.C.M. of 15, 25, 40 and 75 is 600. On dividing 9999 by 600, the REMAINDER is 399. Required number (9999 – 399) = 9600. Greatest number of 4-digits is 9999. L.C.M. of 15, 25, 40 and 75 is 600. On dividing 9999 by 600, the remainder is 399. Required number (9999 – 399) = 9600. |

150 Men Consume 1050 Kg Of Rice In 30 Days. In How Many Days Will 70 Men Consume 980 Kg Of Rice? |
|
Answer» Rate of consumption of each man = 1050/(150 * 30) = 7/30 KG/day Let us say 70 men take x days to consume 150 kg. Quantity CONSUMED by each item in x days = (7x/30) kg Quantity consumed by 70 men in x days = (7/30 x)(70) kg = (7/30 x) * (70) = 960 x = 60 days. Rate of consumption of each man = 1050/(150 * 30) = 7/30 kg/day Let us say 70 men take x days to consume 150 kg. Quantity consumed by each item in x days = (7x/30) kg Quantity consumed by 70 men in x days = (7/30 x)(70) kg = (7/30 x) * (70) = 960 x = 60 days. |

In A Game Of 90 Points A Can Give B 15 Points And C 30 Points. How Many Points Can B Give C In A Game Of 100 Points ? |
|
Answer» While A SCORES 90 points, B scores (90-15)=75 points and C scores (90-30)= 60 points i.e., when B scores 75 points, C scores 60 points => When B scores 100 points, C scores 6075×100 = 80 points i.e., in a game of 100 points, B can give C (100-80)=20 points While A scores 90 points, B scores (90-15)=75 points and C scores (90-30)= 60 points i.e., when B scores 75 points, C scores 60 points => When B scores 100 points, C scores 6075×100 = 80 points i.e., in a game of 100 points, B can give C (100-80)=20 points |

A Train 110 M Long Is Running With A Speed Of 60 Km/hr. In What Time Will It Pass A Man Who Is Running At 6 Km/hr In The Direction Opposite To That In Which The Train Is Going ? |
|
Answer» Speed of train RELATIVE to man = 60 + 6 = 66 km/hr. = 66 * 5/18 = 55/3 m/sec. Time taken to pass the men = 110 * 3/55 = 6 sec. Speed of train relative to man = 60 + 6 = 66 km/hr. = 66 * 5/18 = 55/3 m/sec. Time taken to pass the men = 110 * 3/55 = 6 sec. |
