    From the given statement pass percentage is 48% – 18% = 30%
    Therefore, 30% of x – 20% of x = 10 (marks)
    i.e., 10% of x = 10
    Therefore, x = 100 marks.
  6. 5
    Explanation:
    Let Jayant’s weight be 100 kg.
    So, Maria’s weight = 50 kg.
    Maria’s weight = 50 kgs = 60% of Bobby’s weight
    Or 60/100 of Bobby’s weight = 50 or Bobby’s weight =5000/60=250/3=83.33
    Leena’s weight = 190% of Jayant’s weight = 190% of 100 = 190 kg.
    Divya’s weight = 50% of Leena’s weight = 50% of 190 = 95 kg.
    The smallest of these values is 50 kg. The weight of Maria.
