  6. A person borrowed Rs.16650 on simple interest at the rate of 7% per annum. Find the total amount paid by the person after 4 years.
    Rs. 23050
    Rs. 21312
    Rs. 22520
    Rs. 22000
    Rs. 20202
    Option B
    Total amount paid by the person
    = (16650*7*4)/100 + 16650
    = 4662 + 16650 = Rs. 21312

     

  7. A man has an average speed of 45 km/hr. While going from A to B and returns from B to A with an average speed of x km/hr. Find the value of x, if the average speed of the whole journey is 36 km/hr.
    10 km/hr.
    40 km/hr.
    30 km/hr.
    20 km/hr.
    50 km/hr.
    Option C
    36 = (2*45*x)/(45+x)
    => 36*(45+x) = 90x
    => x = 30 km/hr.

     

  8. X and Y can complete a work together in 24/5 days and Y and Z together and X and Z together can complete the same work in 8 days and 4 days resp. In how many days can Z complete the work alone?
    10
    14
    18
    12
    16
    Option D
    1/x+1/y = 5/24 —–(1)
    1/y+1/z = 1/8 —–(2)
    1/x+1/z = ¼ ——(3)
    From three equations, we get
    2*(1/x+1/y+1/z)=7/12
    => z = 12 days

     

  9. The sum of the present ages of A,B and C is 114 years. The ratio of the present ages of B and C is 3:5 and A’s present age is 10 more than C’s present age. What is the present age of B?
    28
    22
    26
    20
    24
    Option E
    (5x+10)+3x+5x = 114
    => 13x + 10 = 114
    => x = 8
    Present age of B = 24 years

     

  10. R and S can together complete a task in 180/7 days. If the number of days taken by R to complete the task alone is 60 days, then how many days would it take S to complete the task alone?

    40 days
    48 days
    30 days
    37 days
