Question

every year the number of students in a school increases by 15%. one year ago there were 800 students.what will be the number of students one year hence?​

Answer 1

Answer:

Initially the no. is 800. If we take 800 as 100% then after 1st year this will amount to 105% of 800 which is = 840. Then after the second year, 840 will be 100% and at the end of the 2nd year it will be 105% of 840 which will be = 882. Hence, we got the ànswer.

Step-by-step explanation:

Do it like this: Initially there were 800 students and the increased %age is 5%. Just calculate 5% of 800 in your mind. Try this- 10% of 800 is 80. 5% will be half of 10% i.e. 40. Just add 800and 40 for first year which amounts to 840. Similarly, do it for 2nd year. 10% of 840 is 84. 5% will be half i.e. 42. Add up 840+42=882.
