Question

last year, sales at company x were 10% greater in february than in january, 15% less in march than in february, 20% greater in april than in march, 10% less in may than in april, and 5% greater in june than in may. in which month were sales closest to the sales in january?

Answer 1

Let Sales in January,J= 100x
ATQ

sales in Feb,F= ( 1 + 10/100)* J = 1.1*100x = 110x

sales in march,Mr= ( 1 - 15/100)*F = 0.85*110x = 93.5x

sales in April,A = ( 1 + 20/100)*Mr= 1.2*93.5x = 112.2x

sales in may = ( 1 - 10/100)*A = 0.9*112.2x = 100.98x

sales June = ( 1 + 5/100)*may = 1.05*100.98x


clearly sales in may 100.98x are the closest.
