The ratio of water and the remaining portion in a syrup in 89:11. How much liters of water are to be added to the syrup to make the ratio 90:10?

Ratio of water to remaining part of syrup is 89:11


Total parts = 89+11= 100 parts


Let syrup be liters


litres of water and litres of remaining syrup.


When ‘y’ litres of water is added ratio becomes 90:10 i.e. 9:1


Therefore,






⇒ 89 – 100y = 99


⇒ 10 = 10y




So, amount of water to be added is parts of the total syrup.

There are three kinds of liquid in a beverage of 700 liters. The ratio of measurements of the first and the second liquids is 2:3 and the ratio of measurement of the second and the third liquid is 4:5. Let’s work out the ratio in which the first and second liquid will be mixed so that the ratio of measurement of the three liquids become 6:5:3 in the new beverage.

The ratio of the volumes of three bottles is 5:3:2. These three bottles are filled with the solution of phenyl and water. The ratios of measurement of phenyl and water in three bottles each are 2:3, 1:2 and 1:3 respectively. part of the first bottle, part of the second bottle and part of the third bottle are mixed together now. Let’s work out ratio of phenyl and water in the new solution.
