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.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.
