6. Peter got 30% of the maximum marks in an examination and failed by 10 marks. However, Paul who took the same examination got 40% of the total marks and got 15 more than the passing marks in the examination. What were the passing marks in the examination ?
   95
   55
   85
   65
   75
   Option C
   Let the maximum marks be x.
   Then, x × 30% + 10 = x × 40% – 15
   =>x × 10% = 25
   => x = 250
   Passing marks = 250 × 30/100 + 10 = 85

    

7. Rubina decided to donate 16% of her monthly salary to an NGO. On the day of donation she changed her mind and donated Rs. 6,567 which was 75% of what she had decided earlier. How much is Rubina’s monthly salary ?

   Rs. 40025
   Option B
   Let Rubina’s monthly salary be Rs. x.
   According to the question, 75% of 16% of x = 6567
   =>x ×16/100 × 75/100 = 6567
   => x = 6567*100*100/16*75 = Rs. 54725

    

8. A car covers a distance of 528 km. in a certain time at a speed of 66 km./hr. How much distance would a truck cover at an average speed which is 24 km hr. less than that of the speed of the car in time which is 7 hours more than that taken by the car?

   Case II:
   Time =15 hours
   Speed = 66 – 24 = 42 kmph
   Distance covered by truck = Speed × Time

   65(4/3)days
   76(2/3)days
   55(1/3)days
   Option D
   Total time taken to finish the work
   = 10 + 15(210-12)/(15+15*2)
   = 10 + 15*200/45 =10 +200/3
   = 76(2/3)days

    If the rates of interest be r1 and r2% per annum,
    then [2200 *4(r1-r2)]/100
    = 202.40
    => r1-r2 = 202.40*100/2200*4 = 2.3% per annum
