Question

the number of people working for a particular organisation increased by 15% during an year find number of at the beginning of the Year if there were 230 at the end of the year

Answer 1

the people increased by 15%

so at the start let there be x

x + 15/100 of x = 230

115x/100 = 230

x = 230000/115

x = 200

Answer 2

let at the beginning be x then
x +3x/20 = 230
23x = 4600
x =200
so the worker in the beginning is 200
