Suman purchased 100 litres of milk at rs.25 per litre. if 10 litres of milk be lost by leakage, at what rate must the remaining quantity of milk be sold so as to gain 8% on the whole outlay?

rs 30 per litre.

Step-by-step explanation:

We have 90 litres left after the leakage and we paid rs 2500 for it. To gain a 8% profit we have to sell 90 litres for 2500 * 1.08 = rs 2700.

So each litre has to be sold for rs 2700 / 90 = rs 30.

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.
