    Solution

    2 (1/4)% of 7999.78 + {49.77% of 899.71} + √144.14 - 20% of 1499.83 2 (1/4)% of 8000 + {50% of 900} + √144 - 20% of 1500 2 1/4% = 9/4% = (9/400). 9/400 × 8000 = 180. 50% of 900 = (50/100) × 900 = 450. √144 = 12. 20% of 1500 = (20/100) × 1500 = 300. Adding and subtracting: 180 + 450 + 12 - 300   = 342.
