  6. If 2/3 part of an article is sold at 30% profit, 1/4 part at 16% profit and remaining part at 12% profit and finally, there is a profit of Rs.75, then find the cost price of the article.
    500
    600
    400
    100
    300
    Option E
    Here a = 2/3
    b =1/4
    x = 30 %
    y = 16 %
    z = 12 % and R = Rs. 75
    Required CP of article
    = (75*100)/(2/3*30+1/4*16+1/12*12)
    = 7500/25
    = 300

     

  7. Two pipes can fill a tank in 20 and 24 minutes respectively and a waste pipe can empty 3 gallons per minute. All the three pipes working together can fill the tank in 15 minutes. What is the capacity of the tank?
    150 gallons
    120 gallons
    130 gallons
    100 gallons
    80 gallons
    Option B
    Work done by the waste pipe in 1 minute
    = 1/15 − ( 1/20 + 1/24 ) = 1/15 − 11/120 = −1/40
    Volume of 1/40 part = 3 gallons
    Volume of whole = (3 x 40) gallons
    = 120 gallons.

     

  8. Raju got married 8 years ago. His present age is 6/5 times his age at the time of his marriage. Raju’s sister was 10years younger to him at the time of his marriage. Find the present age of Raju’s sister.
    40 years
    18 years
    20 years
    38 years
    35 years
    Option D
    Let Raju’s age at the time of his marriage = x years
    Then from given data => x + 8 = 6x/5
    x = 40.
    Since got married 8 years ago, his present age = 48
    His sister is 10 years younger
    => 48 – 10 = 38 years.

     

  9. A sum of money at simple interest amounts to Rs. 14160 in 3 year. If the rate of interest is increased by 25%, the same sum amount to Rs. 14700 in the same time. Find the rate of interest.
    7%
    3%
    5%
    6%
    4%
    Option D
    14160 = P + (P × R × 3)/ 100
    => 3PR/ 100 = 14160 – P
    => 14700 = P + (P ×1.25R × 3)/ 100
    => P + 5/4 × 3PR/100 = 14700
    => P + 5/4(14160 − P) = 14700
    => 4P + 70800 – 5P = 58800
    => P = 12000
    => 14160 = 12000 + (12000 × R × 3)/100
    => 14160 = 12000 + (120 × R × 3)
    => 14160 – 12000 = 360R
    => 2160 = 360R
    => R = 2160/360 = 6%

     

  10. Twelve persons are seated at a circular table. Find the probability that 3 particular persons always seated together.
    3/50
    4/55
    2/51
    3/55
    3/53
    Option D
    Total probability = (12-1)! = 11!
    Desired probability = (10 – 1)! = 9!
    Required Probability = (9! *3!) /11!
    = 3/55
