Answer 1

A given uber is increased by 20% and the resulting number is again increased by 15%. What is the

net percentage increase in the number?

Answer 2

Step-by-step explanation:

• Let the number be x
• After first increment let it becomes y=x+(20%ofx) = x+20x/100 =6x/5
• Then y is increased by 15%
• Now let z= y+15%ofy = (6x/5) + (15%of 6x/5) =6x/5 + 9x/50 =69x/50
• Percentage increase =[{ (69x/50)- x }/ x] * 100 = 38%
