Question

4. Two equal glasses are respectively 1/3 and
1/4 full of milk. They are then filled up with
water and the contents are mixed in a tumbler.
Find the ratio of milk and water in the
tumbler.
(A) 1:5
(B) 7:17​

Answer 1

Answer:

B) 7:17

Step-by-step explanation:

Let the capacity of each of the two glasses be x

Let's name the glasses as A and B

Consider for glass A ,

milk is 1/3 of total capacity , hence milk = x/3

water = x - x/3 = 2x/3

Consider for glass B ,

milk is 1/4 of total capacity, hence milk = x/4

water = x - x/4 = 3x/4

Now if contents of two glasses are mixed in a pot then

Total milk in pot = x/3 + x/4 = 7x/12

Total water in pot = 2x/3 + 3x/4 = 17x/12

Ratio of milk to water in the pot = ( 7x/12 ) / ( 17x/12 )

= 7 : 17
