Let X's and Y's initial investment for the first 5 months be 30 and 50 After 5 months, X's capital for next 7 months = (150/100) × 30 = 45 Y's capital for next 7 months = (40/100) × 50 = 20 (X's profit)/(Y's profit) = [(30 × 5) + (45 × 7)]/[(50 × 5) + (20 × 7)] ⇒ (150 + 315)/(250 + 140) ⇒ 465/390 ⇒ 31/26 Total profit = 30 + 26 = 57 units ⇒ (X's profit)/(Total profit) = 31/57 ⇒ (X's profit)/6.84 = 31/57 ⇒ X's profit = (31/57) × 6.84 ⇒ X's profit = 3.72

320.98 + 49.99% of (261.09 + 138.98) = ?
20.22 × 11.99 + 140.15 = ?
25.05% of 220.05 – 10.15% of 119.99 × 2.02 = ?
[(80.97) 3/2 + 124.95 of 8% - {(21.02/6.95) × 10.9 × 5.93}]/ 45.08 = ?
72.8% of (215.69 + 189.38) - 5.97² + (3.01 of 7.8) = ? of (64.02 - 38.95)
