Answer 2

15 Litre water must be added to 6 litres

of milk at 1.5 litres for rs 20.

=>C.p of 1.5 =3/2 litre of milk= rs 20

=>C.p of 1 Litre of milk = rs

20×2/3=rs40/3

=>C.p of 1 Litre of water =0

=>Mean price rs 10 2/3=rs 32/3

* We use the rule of alligation

*Cp of 1 Litre of water.*Cp of 1 Litre of

milk.

=O(rs 40/3) mean price(rs32/3-0)

* Ratio of water and milk.

= +8/3:32/3

=8:32

=1:4

*Quantity of milk to be added to 60

litre of milk.

=>(1/4×60)litre

=>15 Litre
