Sectors A, B and C grew by 9% and sectors D, E, F and G grew by 3%. So, Increase in GDP of sectors A, B and C = (A + B + C) × 9% = (100 + 40 + 60) × 9/100 = 18 Similarly increase in GDP of sectors D, E, F & G = (D + E + F + G) × 3% ⇒ (30 + 40 + 65 + 25) × 3/100 = 4.8 So overall growth = 18 + 4.8 = 22.8 Total GDP before growth = 360 So, overall growth % = 22.8/360 × 100 = 6.33%
