Answer 20- 4% increase
Reason - cross elasticity measures the responsiveness in demand of one good with change in price of another good. A negative cross elasticity denotes two products that are complements, while a positive cross elasticity denotes two substitute products. As there is a positive cross elasticity present here, fish is a substitute of chicken. So with increasing price of fish the demand for fish will fall and people will start shifting to chicken. And as the elasticity is twice the shifting will increase the demand of chicken by 4%.
