    1. Quantity I: Find the time period if a sum of Rs.2500 becomes Rs. 2950 at 9% SI per annum.
      Quantity II: Find the time period if a sum of Rs.2500 earns Rs.525 as interest at 10% CI per annum compounded annually.
      Quantity III: Find time period if a sum of Rs. 2000 amounts to Rs.2928.2 at 20% CI per annum compounded Half – Yearly
      1. Q1>Q2>Q3
      2. Q2>Q3>Q1
      3. Q3>Q2>Q1
      4. Q2>Q1>Q3
      5. Q1=Q2=Q3
      Answer – 5. Q1=Q2=Q3
      Q1 :450 = 2500*9*t/100 = 2
      Q2: 3025 =2500(1+10/100) t = 2
      Q3. 2928.2 = 2000(1+10/100) 2t = 2

    2. Ravi, Ramu, Raju invested in the ratio of 5:6:7 respectively. At the end of the business, they received the profit in the ratio of 10:8:7.
      Quantity I: Time period for which Ravi invested?
      Quantity II: Time period for which Ramu invested?
      Quantity III: Time period for which Raju invested?
      1. Q1>Q2>Q3
      2. Q1>Q3>Q2
      3. Q2>Q3>Q1
      4. Q1=Q2=Q3
      5. Relationship cannot be established
      Answer – 1. Q1>Q2>Q3
      let times be t1,t2, and t3
      5t1/6t2 = 10/8
      t1:t2 = 3:2
      similarly t2:t3 =4:3
      t1:t2:t3 = 6:4:3
