Let the volumes be 3x,4x,5x respectively.
Container with volume 3x,
Milk = [4/(4+1)] × 3x
Water = [1/(4+1)] × 3x
Container with volume 4x,
Milk = [3/(3+1)] × 4x
Water = [1/(3+1)] × 4x
Container with volume 5x,
Milk = [5/(5+2)] × 5x
Water = [2/(5+2)] × 5x
Total milk = 12x/5 + 12x/4 + 25x/7 = 1256x/140
Total water = 3x/4 + 4x/4 + 10x/7 = 424x/140
Ratio of milk to water in 4th container = 1256/424 =157:53
Speed of boat is 15 km/hr. Speed of the stream is 20% less than speed of boat. Then find time taken by boat to go 108 km downstream?
A man row a boat 1 km in 5 min, along the stream and 6 km in 1hrs against the stream, The speed of the stream will be
Ratio of speed of boat in downstream and speed of stream is 5:2, if speed of current is 4 km/hr, then find distance travelled (in km) upstream in 6 hours.
