Train X starts from A towards B which is 180 Kms apart. At same time, train Y start from B towards A. Train X travels at speed of 70 kmph and Y travels at 50 kmph. While X does not stop anywhere on the way, the train Y stops at station C in between at 60km from B for 15 minutes. At what distance from A they would meet
Let the meet at a distance x km from A.
So x/70 = (180-x)/50 + 1/4
or, 100x/70 = 360-2x+25
or, 10x = 2520 - 14x + 175
or, 24x = 2695
or, x = 2695/24 = 112.3km

Question :
A boat takes 90 minutes less to travel 36 miles downstream than to travel the same distance upstream. If the speed of the boat in still water is 10 mph, the speed of the stream is:
Let the speed of the stream x mph. Then, Speed downstream = (10 + x) mph, Speed upstream = (10 - x) mph. 36 /(10 - x) - 36 /(10 + x) = 90/60 (72x )* 60 = 90 (100 - x2) x2 + 48x + 100 = 0 (x+ 50)(x - 2) = 0 x = 2 mph.

Salaries of Ravi and Sumit are in the ratio 2 : 3. If the salary of each is increased by Rs. 4000, the new ratio becomes 40 : 57. What is Sumit's salary?
Angle traced by hour hand in 17/2 hrs = (360/12)*(17/2) = 255 º
Angle traced by min. hand in 30 min. = (360/60)*(30) = 180 º
Required angle = (255 - 180)º = 75º.

Question :
Assume integer is 2 bytes wide. How many bytes will be allocated for the following code?
Step 1: x=y=z=1; here the variables x ,y, z are initialized to value '1'.
Step 2: z = ++x || ++y && ++z; becomes z = ( (++x) || (++y && ++z) ). Here ++x becomes 2. So there is no need to check the other side because ||(Logical OR) condition is satisfied.(z = (2 || ++y && ++z)). There is no need to process ++y && ++z. Hence it returns '1'. So the value of variable z is '1'
Step 3: printf("x=%d, y=%d, z=%d
", x, y, z); It prints "x=2, y=1, z=1". here x is increemented in previous step. y and z are not increemented.
