Then, 12/100 = x/60 → x = 7.2 ml Therefore, 7.2 ml is present in 60 ml of water. So in order to get a 8% chlorine solution, we need to add 90-60 = 30 ml of water.In order for this 7.2 ml to constitute 8% of the solution, we need to add extra water. Question: There is a 20 litres of a solution which has 20% of bleach.Question: In a certain room, there are 28 women and 21 men. What is the ratio of women to the total number of people?
If the total number of people in the group is 72, what is the number of lawyers in the group? Question: In a bag, there are a certain number of toy-blocks with alphabets A, B, C and D written on them.
Solution: Let the number of doctors be 5x and the number of lawyers be 4x. The ratio of blocks A: B: C: D is in the ratio 4:7:3:1.
Therefore, 5/6 = 20/____To get 20 in the numerator, we have to multiply 5 by 4. 6 by 4Thus, 5/6 = 20/6 × 4 = 20/24Hence, the required numbers is 243. Therefore, 12, x, 8 and 14 are in proportion i.e., 12 : x = 8 : 14⇒ x × 8 = 12 × 14, [Since, the product of the means = the product of the extremes]⇒ x = (12 × 14)/8⇒ x = 21Therefore, the second term to the proportion is 21.
The first, third and fourth terms of a proportion are 12, 8 and 14 respectively.
Extra bleach is added to it to make it to 50% bleach solution. So, for each kg of cashews added, let’s consider it as ‘-5’ and for each kg of walnuts added, let’s consider it as ‘ 15’.
How much water has to be added further to bring it back to 20% bleach solution? In the first part, there is 20% of bleach in 20 L of solution → 4 L of bleach in 16 L of water = 20 L of solution. These two have to be added in such a way that they cancel out each other.
If the number of ‘A’ blocks is 50 more than the number of ‘C’ blocks, what is the number of ‘B’ blocks?
Solution: Let the number of the blocks A, B, C, D be 4x, 7x, 3x and 1x respectively 4x = 3x 50 → x = 50. Question: If the ratio of chocolates to ice-cream cones in a box is 5:8 and the number of chocolates is 30, find the number of ice-cream cones.
Therefore, 45 litres of sugar solution has to be added to bring it to the ratio 2:1.
Question: A certain recipe calls for 3kgs of sugar for every 6 kgs of flour.
