I did in usual way.. pretty lengthy one...

Dick -> increased by 8% of 3000 = 240 , so Dick share in 1990 will be 3240.
Jane --> decreased by x% of 3000, so Jane share in 1990 will be \(3000(1- x/100 )\)

\(3240 + 3000 (1- x/100 ) = 5000\)

\(1- x/100 = 166 / 300\)

x= 41% (approx)

given jane 1989 - 3000
dick 1989 - 3000

1990 = D + J = 5000

dick 8 percent more = 3000 * 8/100 = 240 >> 3000 + 240 = 3240

jane = 5000-3240 = 1760

to find the decrease new - old/old * 100

1760 - 3000 / 3000 * 100

1240 / 3000 * 100 = 124/3 = 41% approx

Answer Choice C
