Question
Select the correct answerThe ratio of the number of students studying in a school A, B and C is 5:6:8. If the number of students studying in each of the schools is increased by 30%, 25% and 25% respectively, what will be the new ratio?Options13:15:2014:15:2013:14:1515:17:19
Solution
The first step is to understand the initial ratio of students in schools A, B, and C, which is 5:6:8.
Next, we need to calculate the new number of students in each school after the increase.
For school A, the number of students is increased by 30%. So, the new ratio for A would be 5 * 1.30 = 6.5.
For school B, the number of students is increased by 25%. So, the new ratio for B would be 6 * 1.25 = 7.5.
For school C, the number of students is increased by 25%. So, the new ratio for C would be 8 * 1.25 = 10.
So, the new ratio of students in schools A, B, and C would be 6.5:7.5:10.
However, ratios should be expressed in whole numbers. To convert the ratio to whole numbers, we can multiply each term by 2, which gives us 13:15:20.
Therefore, the correct answer is 13:15:20.
