Let the charges at Sherato, Westin and Sonargaon be A, B & C respectively. Now, A = B - 25% of B = B - 0.25B = 0.75B = 3B/4 or, B = 4A/3 Again, A = C - 10% of C = C - 0.1C = 0.9C = 9C/10 or, C = 10A/9 Now, B - C = 4A/3 - 10A/9 = (12A - 10A) / 9 = 2A/9 Charge at westin is greater than charge at Sonargaon by (2A/9) / (10A/9) × 100% = 20%
