A factory manufactures two types of widgets, A and B, in
the ratio of 4:5. If the production of widget A rises by 20% while the production of widget B decreases by 12%, what will be the new ratio of widgets A to B?Solution
Let the production of widget A = 4x And, production of widget B = 5x production of widget A after increasing by 20% = 120% of 4x = 4.8x production of widget B after decreasing by 12% = 88% of 5x = 4.4x required ratio = 4.8x: 4.4x = 12: 11
