Question

Q there are two vessels a and b in which the ratio of milk and water are as 5:2 and 8:7 respectively. two gallons are drawn from vessel a and 3 gallons from vessel b, and are mixed in another empty vessel. what is the ratio of milk and water in it?

Answer 1

If 2 gallons are taken from A, the quantity of milk & water=2*5/7:2*2/7=10/7:4/7

If 3 gallons are taken from B,the quantity of milk & water=3*8/15:3*7/15=8/5:7/5

Now in the new mixture qtantity of milk 10/7+8/5=106/35 & water 4/7+7/5=69/35

Therefore ratio of milk:water=106/35:69/35=106:69 ANS
