] | B | Let their speed be x km/hr and y km/he respectively.
Then, 120/(x + y) = 1 => x + y = 120 --- (i)
Now, when they move in same direction:
(Distance traveled by P in 6 hrs) - (Distance traveled by Q in 6 hrs) = 120 km
6x - 6y = 120 => x - y = 20 --- (ii)
Sloving (i) and (ii), we get x = 70, y = 50

At what time between 7 and 8 o'clock will the hands of a clock be in the same straight line but, not together? | [
"5x5/11 min past 7",
"5/22 min past 7",
"5x5/22 min past 7",

When the hands of the clock are in the same straight line but not together, they are 30 minute spaces apart.
At 7 o'clock, they are 25 min. spaces apart.
Minute hand will have to gain only 5 min. spaces.
55 min. spaces are gained in 60 min.
5 min. spaces are gained in60/55x 5 min = 5X 5/11 min.

] | D | $19500 is a fixed cost
Each component is $151 ($150 to produce, $1 to ship)
Manufacturer will be producing and selling 250 components
so therefore the equation to find price would be
