  • Answers:

  • Sadao’s expertise in his profession and compassion as a human being were his most dominant personality traits. As a dutiful doctor, he could not have let the prisoner die of his injuries and so he saved his life. At the same time, he acted like a responsible citizen and informed the General of the presence of the enemy. However, when the General’s men did not come to kill the American Sadao decided to save his life.

    Dr Sadao gave his boat to the young soldier, arranged food for him and provided him valuable information which helped him escape successfully. This is how Sadao helped the American soldier flee and thereby saved his life.

    Then no of ₹100 she have will have is (25-x).

    According to question equation will be

    50x+100(25-x)=2000

    2500-50x=2000

    x=500/50

    x=10

    Then she have 10 notes of ₹50 and 25-10=15 notes of ₹ 100.

  • Let no of Rs. 50 notes = x

    No of Rs. 100 notes = 25 - x.

    50 x + 100(25 -x) = 2000

    50x + 2500 - 100x = 2000

    50x = 500

    x = 10 notes 

    y = 25-10 = 15 notes

  • Answers:
  • Given 

    Force = 100N

    Pressure = 500Pascel

    We know 

    {tex}Pressure = {force \over Area}{/tex}

    So,

    {tex}500={100\over area}{/tex}

    {tex}=> area={100\over 500}{/tex}

    {tex}=> area=0.2 m^2{/tex}
