Validate

Solution:

(a ) If we assume that quantity of mixture in all three containers are 5, 4 and 5, then total quantity of milk
=

1/6

x 5 +

3/8

x 4 +

5/12

x 5
=

5/6+3/2+25/12

{10+ 18 + 25}/12 = 53/12

L
and quantity of water = (5 + 4 + 5 ) -

53/12=115/12

L
∴ Required ratio=

53/12:115/12

= 53 : 115
