    Solution

    2 (1/4)% of 7999.58 + {49.06% of 898.87} + √143.14 – 19.99% of 1499.63 - (52 - 41)  2 (1/4)% of 8000 + {50% of 900} + √144 - 20% of 1500 - (52 – 41) 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. 52 - 41 = 11. Adding and subtracting: 180 + 450 + 12 - 300 - 11 = 331. Correct answer: b)
