  7. The area of a rectangle gets reduced by 9 square units,if its length is reduced by 5 units and breadth is increased by 3 units. If we increase the length by 3 units and breadth by 2 units, then the area is increased by 67 square units. Find the area of the rectangle?
    163
    174
    153
    169
    175
    Option C
    then the area is increased by 67 square units. Find the area of the rectangle?
    Length = x; Breadth =y
    xy – (x-5)(y+3) = 9
    3x – 5y – 6 = 0 —(i)
    (x+3)(y+2) – xy = 67
    2x + 3y -61 = 0 —(ii)
    solving (i) and (ii)
    x = 17m ; y = 9m
    Area of the Rectangle = 153 m

     

  8. The average salary of all the employees in company is 7000. The average salary of 9 mechanic is 5000 and for the rest of the employees it 4000. Find the total number of employees in the company.

    7000*E = 9*5000 + (E-9)*4000.
    E = 3
    Hence, 3+9 =12

     

  9. A number is first decreased by 25%. The decreased number is then increased by 20%. The resulting number is less than the original number by 40. Find the original number.
    345
    450
    400
    370
    330
    Option C
    Let the number is x.
    x – (75/100)*x*(120/100) = 40
    x = 400

    2/17
    3/13
    1/15
    Option D
    Total caps = 14
    Probability = 5c0 * 9c3/ 14c3 = 3/13
