Quantity of milk in five vessels


Quantity of water in five vessels

1
Quantity of milk in vessels A and E together is what percent of quantity of water in vessel D?
» Explain it
C
Total quantity of milk =  2  × 2400 = 1600 litres.
3

Total quantity of water = 2400 – 1600 = 800 litres.

Quantity of milk in vessels A and E together
12 + 28  × 1600 = 640 litres
100

Quantity of water in vessel D
25  × 800 = 200 litres
100

Reqd. % =  640  × 100 = 320%
200

Hence, option C is correct.
 
2
Find the respective ratio of quantity of water in vessels B and C together and quantity of milk in vessel D.
» Explain it
A
Total quantity of milk

2  × 2400 = 1600 litres.
3

Total quantity of water = 2400 – 1600 = 800 litres.

Quantity of water in vessels B and C together
15 + 10  × 800 = 200 litres
100

Quantity of milk in vessel D
20  × 1600 = 320 litres
100

Required ratio = 200 : 320 = 5 : 8

Hence, option A is correct.
 
3
Another vessel F also contains a mixture of milk and water. Quantity of milk in vessel F is 20% more than the quantity of milk in vessel C and quantity of water in vessel F is 20% less than the quantity of water in vessel C. Find the respective ratio of milk and water in vessel F.
» Explain it
B
Total quantity of milk =  2  × 2400 = 1600 litres.
3

Total quantity of water = 2400 – 1600 = 800 litres.

Quantity of milk in vessel C
8  × 1600 = 128 litres
100

Quantity of milk in vessel F
= 128 ×  120  = 153.6 litres
100

Quantity of water in vessel C
10  × 800 = 80 litres
100

Quantity of water in vessel F
= 80 ×  80  = 64 litres
100

Required ratio = 153.6 : 64 = 12 : 5

Hence, option B is correct.
 
4
Find the sum of quantity of milk in vessels B and D together and quantity of water in vessels D and E together.
» Explain it
B
Total quantity of milk =  2  × 2400 = 1600 litres.
3

Total quantity of water = 2400 – 1600 = 800 litres.

Quantity of milk in vessels B and D together
32 + 20  × 1600 = 832 litres
100

Quantity of water in vessels D and E together
25 + 20  × 800 = 360 litres
100
Required sum = 832 + 360 = 1192 litres.

Hence, option B is correct.
 
5
Quantity of mixture in vessel C is what percent more/less than the quantity of mixture in vessel E?
» Explain it
C
Total quantity of milk =  2  × 2400 = 1600 litres.
3

Total quantity of water = 2400 – 1600 = 800 litres.

Quantity of milk in vessel C
8  × 1600 = 128 litres
100

Quantity of water in vessel C
10  × 800 = 80 litres
100

Quantity of mixture in vessel C= 128 + 80 = 208 litres

Quantity of milk in vessel E
28  × 1600 = 448 litres
100

Quantity of water in vessel E
20  × 800 = 160 litres
100

Quantity of mixture in vessel E = 448 + 160 = 608 litres
 
Reqd. % =  608 – 208  × 100
608

400  × 100 = 65.78% less
608

Hence, option C is correct.
