Two trains X and Y start at the same time in the opposite direction from two points P and Q and arrive at their destinations 36 and 25 hours respectively after their meeting each other. At what speed does the second train Y travel if the first train travels at 80 km/h.?koi h ❤☺✌foĺlow me |
|
Answer» Answer: LET speed of Train B = x 120/x= √(9/16) => x = 4 x 120/3 = 160 km/hr Note : This can be solved without using this formula by using fundamentals of TIME, Speed & Distance. Step-by-step explanation: Derivation of formula : Let x be the total distance and t be the time at which the two trains MEET. Let s1, s2 are speeds of train A, train B RESPECTIVELY and a & b are the times at which they reach the destination after they meet. x = t(s1 + s2) ...(1) x = (t + a)s1 ...(2) x = (t + b)s2 ...(3) Solving (1), (2) & (3) t = √(a*b) => Time to meet is the Geometric Mean of individual time after meeting. => s1/s2 = √(b/a) ☺hope that's help you |

DDirections for Questions 67 and 68: Amitesh buys apen, a pencil and an eraser for 41. If the least cost of anyof the three items is 12 and it is known that a pen costsless than a pencil and an eraser costs more than a pencil,answer the following questions:67. What is the cost of the pen?(a) 12(b) 13(c) 14(d) 1568. If it is known that the eraser's cost is not divisibleby 4, the cost of the pencil could be:(a) 12(b) 13(c) 14(d) 1560 |
|
Answer» Answer: 67. given least cost is 12. and pen<PENCIL & eraser>pencil so pen hence the least one will be pen which is 12 Right answer is A 68. to get this answer we have to use each of the options given here. a. pen cost is 12. and we know pen b. if pencil cost is 13 then eraser cost = 41-(12+13)=16 which is divisible by 4 hence cost of pencil can't be 13. C. if pencil cost is 14 then eraser cost = 41-(12+14)= 15 which is not divisible by 4 and also pen d. if pencil cost is 15 then eraser cost = 41-(12+15) = 14 which is not divisible by 4 but pen So right answer is C |

Answer» Answer: 75 100 Explanation: There are a few ways to visualise this but I will chose what I THINK is the simplest If you know decimal places you can determine what value should be in the denominator of the fraction, let's use the example number 123.45 In the example 3 is in the ones place, 2 is in the tens place and 1 is in the HUNDREDS place Decimals work the same way except backwards, for our example 4 is in the tenths place and 5 is in the hundredths place (notice the "TH" at the ends) If you can determine what the last decimal place is, then you simply place it over that value (so in the tenths place you use 10 as the denominator and so one) So for your QUESTION the 5 is in the hundredths place so you place the whole number over one hundred You then simplify 75/100 to 3/4 (both values are divisible by 25, 75/25=3 and 100/25=4 |

Answer» Given : 1296 toffees were distributed amongst A, B, C and D such that A got twice as much as C and B got thrice as much as D. If A got 20 less toffees than B, To find : the sum of toffees with A and D. Solution: A got twice as much as C => A = 2C B got thrice as much as D => B = 3D A got 20 less toffees than B A = B - 20 => 2C = 3D - 20 Total A + B + C + D = 1296 => 2C + 3D + C + D = 1296 => 3C + 4D = 1296 2C = 3D - 20 => 6C = 9D - 60 3C + 4D = 1296 => 6C + 8D = 2592 => 9D - 60 + 8D = 2592 => 17D = 2652 => D = 156 B = 3D = 3 * 156 = 468 A = B - 20 = 468 - 20 = 448 A + D = 448 + 156 => A + D = 604 A 448 B 468 C 224 D 156 sum of toffees with A and D is 604 Learn More A total of 40 apples are distributed among A, B, C, D, E AND F.
