Explanation:
4 | x y = (5 x 1 + 4) = 9
——–
5 | y -1 x = (4 x y + 1) = (4 x 9 + 1) = 37
——–
| 1 -4
Now, 37 when divided successively by 5 and 4, we get
5 | 37
———
4 | 7 – 2

Answer: Option D
Explanation:
Let the original salaries of Ravi and Sumit be Rs. 2x and Rs. 3x respectively.
| Then, | 2x + 4000 | = | 40 |
| 3x + 4000 | 57 |
57(2x + 4000) = 40(3x + 4000)
6x = 68,000
3x = 34,000
Sumit’s present salary = (3x + 4000) = Rs.(34000 + 4000) = Rs. 38,000.

Then, relative speed of the two trains = 2x m/sec.
| So, 2x = | (120 + 120) |
| 12 |
2x = 20
x = 10.
| Speed of each train = 10 m/sec = | 10 x | 18 | km/hr = 36 km/hr. | ||
