√(10 + √25 + √108 + √154 + √225)

= √(10 + (√25 + (√108 + (√154 + (√225))))

= √(10 + (5 + (√108 + (√154 + 15))))

= √(10 + (5 + (√108 + (13))))

= √(10 + (5 + (√108 + 13)))

= √(10 + (5 + (11)))

= √(10 + (6))

= √16

= 4

|-4| = 4

|+4| = 4

Sum = 4 + 4 = 8

Explanation

Original sum = 10 × 15 = 150

Correction: +36 -26 = +10

New sum = 150 + 10 = 160

Correct average = 160/10 = 16

Explanation

Cost Price = 80,000

Selling Price = 88,000

Profit = 88,000 - 80,000 = 8,000

Profit % = (8000/80000) × 100 = 10%

Explanation

Even numbers: 2, 4, 6...100

Count = 50

Sum = n/2 × (first + last) = 50/2 × (2 + 100) = 25 × 102 = 2550

Average = 2550/50 = 51

Total area = 40 × 30 = 1200 ft²

Uncut area = 20 × 15 = 300 ft²

Fraction uncut = 300/1200 = 1/4
