Question
Three individualsāAman,
Bittu, and Rajuāeach complete a distance of 120 meters in different time durations: 'x' seconds for Aman, 'x - 2' seconds for Bittu, and 'x + 3' seconds for Raju. Additionally, the ratio of Aman's speed to Raju's speed is given as 5:4. Quantity I: If Bittu and Raju compete in a 300-meter race, how much distance will separate them when the winner crosses the finish line? Quantity II: If Aman and Raju compete in a 320-meter race, how much distance will separate them when the winner crosses the finish line? In the question, two quantities i.e. Quantity I and Quantity II are given. Solve the given quantities to establish the correct relation between them and choose the correct option.Solution
ATQ, 120 = 5 Ć x = 4 Ć (x + 3) 5x = 4x + 12 x = 12 Speed of Aman = 120/12 = 10 m/s Speed of Bittu = 120/(12 - 2) = 120/10 = 12 m/s Speed of Raju = 120/(12 + 3) = 120/15 = 8 m/s Quantity I, Distance between Bittu & Raju, when winner finish the race = 300 - 300/12 Ć 8 = 300 - 200 = 100 m Quantity II, Distance between Bittu & Raju, when winner finish the race = 320 - 320/10 Ć 8 = 320 - 256 = 64 m Quantity I > Quantity II
If āy + (1/āy) = 10, then find the value of y + (1/y).
(x + 4) 2 + (y ā 1) 2 + (z + 2) 2 = 0, then find the value of 2x - 3y + z.
If, 3x + 2y = 15, and 2xy = 12, and 3x > 2y, then find the value of 27xĀ³ ā 8yĀ³.
If (10 aĀ³ + 4bĀ³): (11aĀ³ ā 15bĀ³) = 7:5, then (3a + 5b): (9a - 2b) = ?
