Answer 1

Answer:

Step-by-step explanation:

Quantity of milk bought= 28 litres

rate of milk= 8.50/litre

total CP of milk=28*8.5

=238 rupees

let the amount of water added be x

so after adding the water CP=SP

p%=p/cp*100

p=12.5/100*238

p=1/8*238

=29.75

so, SP=238-29.75

=208.25

28+x*8.5

238+8.5x

208.25- 238+8.5x=29.75

so, x=0

no water added
