In India’s exports increased by 20% from 1998-1999 to 2002-2003, then find the approximate percentage increase in the exports of the engineering goods from 1998-1999 to 2002-2003

Solution

1998-99

India exports be t

Manufacturing goods = 73.6/100 * t

engineering goods = 12.5/100 * 73.6/100 * t = 920t/10000

2002-03

India exports = 1.2t

Manufacturing goods = 77.4/100 *1.2 t

engineering goods = 16.6/100 * 77.4/100 *1.2 t = 1541.808t/100

% increase = 1541.808-920/920 = 67.5%
