Question

mangoes costed rs 50 a kg.the cost went up by 20% n.later the cost went down by 10%. by what percent is thefinal cost above the initial cost?

Answer 1

Step-by-step explanation:

initial cost=Rs.50

cost went up by 20%

therefore ,increase=20/100×50=Rs.10

new cost =50+10=Rs.60

cost went down by 10%

therefore,decrease=10/100×60=Rs 6

new cost=60-6=54

now,final cost=54

initial cost =50

increase in cost=54-50=4

increase%= increase/initial value×100

=4/50×100

=8%

therefore, the final cost is above the initial cost by 8%
