A distance of \(\dfrac{1}{2}\) centimetre on a map represents 200 kilometre on the ground. If two cities are 1800 kilometre apart on the ground, then their distance on the map will be1. nine centimetre2. three and a half centimetre3. four and a half centimetre4. six centimetre |
|
Answer» Correct Answer - Option 3 : four and a half centimetre Given : 1/2 cm on map = 200 km on ground Calculation 1/2 cm on map = 200 km on ground ⇒ 1 cm on map = 400 km on ground or 1 km in ground = 1/400 cm on map ∴ 1800 km on ground = 1800 ÷ 400 = 4.5 cm on map. So, the correct answer is option 3) four and a half-centimeter. |

|
Answer» Correct option (d) 8 Explanation: If the difference between the 6th and the 1st term is 30, it means that the common difference is equal to 6. Since, the third term is 16, the AP would be 4, 10, 16, 22, 28, 34, 40, 46 and the sum to 8 terms for this AP would be 200. |

In Narora nuclear power plant a technician is allowed an interval of maximum 100 minutes. A timer with a bell rings at specific intervals of time such that the minutes when the timer rings are not divisible by 2, 3, 5 and 7. The last alarm rings with a buzzer to give time for decontamination of the technician. How many times will the bell ring within these 100 minutes and what is the value of the last minute when the bell rings for the last time in a 100 minute shift? |
|
Answer» In order to find how many times the alarm rings we need to find the number of numbers below 100, which are not divisible by 2, 3, 5 or 7. This can be found by: 100 — (numbers divisible by 2) – (numbers divisible by 3 but not by 2) — (numbers divisible by 5 but not by 2 or 3) — (numbers divisible by 7 but not by 2 or 3 or 5). Numbers divisible by 2 up to 100 would be represented by the series 2, 4, 6, 8, 10…100 → A total of 50 numbers. Numbers divisible by 3 but not by 2 up to 100 would be represented by the series 3, 9, 15, 21...99 → A total of 17 numbers. Note use short cut for finding the number of number in this series : [(last term — first term)/ common difference] + 1 = [(99 — 3)/6] + 1 = 16 + 1 = 17. Numbers divisible by 5 but not by 2 or 3: Numbers divisible by 5 but not by 2 up to 100 would be represented by the series 5, 15, 25, 35...95 → A total of 10 numbers. But from these numbers, the numbers 15, 45 and 75 are also divisible by 3. Thus, we are left with 10 — 3 = 7 new numbers which are Divisible by 5 but not by 2 and 3. Numbers divisible by 7, but not by 2, 3 or 5: numbers divisible by 7 but not by 2 upto 100 would be represented by the series 7, 21, 35, 49, 63, 77, 91 → A total of 7 numbers. But from these numbers we should not count 21, 35 and 63 as they are divisible by either 3 or 5. Thus a total of 7 — 3 = 4 numbers are divisible by 7 but not by 2, 3 or 5. Thus we get a total of 100 − 78 = 22 times. Also, the last time the bell would ring would be in the 97th minute (as 98, 99 and 100 are divisible by at least one of the numbers). |

The internal angles of a plane polygon are in AP. The smallest angle is 100° and the common difference is 10°. Find the number of sides of the polygon. |
|
Answer» Smallest interior angle = 100, largest exterior angle= 180 − 100 =80 Similarly other exterior angles are 70, 60, 50, …. Sum of all the exterior angles = 360 So n(2.80 +(n-1)(-10))/2 = 360 or n(17 − n) = 72 We can see that the above equation is true for both n = 8, 9. But for n = 9, the 9th exterior angle must be 0 which is not possible so only 8 is possible. |

The sum of the squares of 3 natural numbers is 261, and they are in the proportion 2 : 3 : 4. The difference between greatest number and smallest number is:1. 62. 93. 54. 4 |
|
Answer» Correct Answer - Option 1 : 6 Calculation: Let the numbers be 2y, 3y and 4y respectively. ⇒ (2y)2 + (3y)2 + (4y)2 = 261 ⇒ 29y2 = 261 ⇒ y2 = 9 ⇒ y = 3 Greatest number = 4y = 12 Smallest number = 2y = 6 ∴ The difference between greatest number and smallest number is 6.

A man purchases some mangoes at the rate of 24 mangoes for Rs 1. How many mangoes did he sell for a rupee to gain 20% profit?1. 202. 213. 184. 22 |
|
Answer» Correct Answer - Option 1 : 20 GIVEN: A man purchases some mangoes at the rate of 24 mangoes for Rs. 1. CONCEPT: FORMULA USED: SP = CP × [1 + Profit/100] CALCULATION: Given, CP of 24 mangoes is Rs. 1. ⇒ CP per mango = Rs 1/24 Also, Profit = 20 % of CP = 1/5 CP So, SP = CP + Profit = 6/5 CP. ⇒ SP per mango = Rs 6/5 × 1/24 = 1/20 Since, SP of 1 mango = Rs 1/20 ⇒ No. of Mangoes sold for Rs. 1 = 20 |

Shashank had candies and chewing gums in his sweet box in the ratio 7 ∶ 13. After he has eaten 9 candies and 11 chewing gums the ratio became 1 ∶ 2. How many candies does he have now?1. 442. 423. 414. 40 |
|
Answer» Correct Answer - Option 4 : 40 Given: Shashank had candies and chewing gums in his sweet box in the ratio 7 ∶ 13. Calculations: Let the number of candies be 7x and the number of chewing gums be 13x. According to the question, (7x – 9)/(13x – 11) = 1/2 ⇒ 14x – 18 = 13x – 11 ⇒ 14x – 13x = 18 – 11 ⇒ x = 7 Number of remaining candies = 7x – 9 = (7 × 7) – 9 = 49 – 9 = 40 ∴ Number of remaining candies is 40 |

The ratio of three numbers A, B and C is 8 ∶ 11 ∶ 15, and ratio of A and D is 4 ∶ 11. The number C is equal to the average of the number A and D. Find the number B.1. 332. 243. 454. Cannot be determined |
|
Answer» Correct Answer - Option 4 : Cannot be determined Given: The ratio of three numbers A, B and C = 8 ∶ 11 ∶ 15 The ratio of A and D = 4 ∶ 11 The number C = The average of the numbers A and D. Formula: If the ratio of A and B is a ∶ b, assume A = ak and B = bk where k is a constant. Calculation: Let the numbers A, B, C and D be 8x, 11x, 15x and 22x respectively. The number C = The average of the numbers A and D. ⇒ 15x = (8x + 22x)/2 ⇒ 30x – 8x = 22x ⇒ 22x = 22x ∴ The value of x cannot be determined. A : B : C = 8 : 11 : 15 A : D = 4 : 11 To make A same in both the ratios , we have to multiply 2 with (A : D) |

Three boys A, B and C got different number of pens. If A gives 3 pens to C, then the ratio of the number of pens of A and C becomes 19 ∶ 28. If B gives 2 pens to C, then the ratio of the number of pens of B and C will be 7 ∶ 11. The number of pens with B is 37. Find the number of pens with A.1. 532. 333. 414. 55 |
|
Answer» Correct Answer - Option 3 : 41 Given: If A gives 3 pens to C, ratio becomes = 19 ∶ 28. If B gives 2 pens to c, ratio becomes = 7 ∶ 11 The number of pens with B = 37 Calculation: Let the pens with A, B and C be a, b and c respectively. If B gives 2 pens to c, ratio becomes = 7 ∶ 11 ⇒ (b – 2)/(c + 2) = 7/11 ⇒ (37 – 2)/(c + 2) = 7/11 ⇒ 385 = 7(c + 2) ⇒ c = 53 Now, If A gives 3 pens to C, ratio becomes = 19 ∶ 28 ⇒ (a – 3)/(c + 3) = 19/28 ⇒ (a – 3)/(53 + 3) = 19/28 ⇒ a = 38 + 3 ⇒ a = 41 ∴ The number of pens with A is 41. |

Amit covers from A to B and back to A by train in 16 hour. If the ratio of speed from A to B and back from B to A is 5 : 3. Find the speed of the train in the onward journey from A to B if the distance between A and B is 300 kilometres.1. 50 km/hr2. 30 km/hr3. 25 km/hr4. 45 km/hr5. 15 km/hr |
|
Answer» Correct Answer - Option 1 : 50 km/hr Given: Total time = 16 hours Total distance = 600 km The ratio of speed of onward journey and return journey is 5 : 3 . Formula used : Average speed = Total distance/Total time taken Average speed = 2 x y/x + y Where, x and y are speeds of onward journey and return journey respectively . Calculations : Let speed of onward journey and return journey be 5x and 3x respectively. Average speed = 600/16 ----(1) Also, Average speed = 2 × 5x × 3x/(5x +3x) ----(2) On equating equation (1) and (2) we get , ⇒ 2 × 5x × 3x/(5x +3x) = 600/16 ⇒ 30x2/8x = 600/16 ⇒ x = 10 ⇒ speed of onward journey is 5x = 5 × 10 = 50 km/hr ∴ The speed of train in onward journey from A to B is 50 km/hr. |
