    Solution

    ATQ, Leena’s score = Jai's score - 30 = 95 - 30 = 65 Neha’s score = Leena's score + 45 = 65 + 45 = 110 Omar’s score = Neha's score - 32 = 110 - 32 = 78 Karan’s score in the first test = Omar's score - 22 = 78 - 22 = 56 Total maximum marks of tests = 150 + 180 = 330 Karan has to score 60% of 330 = 330 × (60/100) = 198 marks Remaining required marks = 198 - 56 = 142 Required % = (142/180) × 100 = 78.8889% or 79%
