  • Question 1/10
    1 / -0

    Product of one fourth of the number  and 120% of another number is what % of the product of the original number ?

    Solutions

    Explanation :

    x/4 = one fourth of the no

    120y/100 = another no = 6y/5

    % = [(x/4 * 6y/5)*100] / xy

    = 600/20 = 30%

     

  • Question 2/10
    1 / -0

    When a number is subtracted from the number 8,12 and 20, the remainders are in continued proportion, Find the number ?

    Solutions

    Explanation :

    8-x / 12 –x = 12-x /20 –x

    (8-x)(20-x) = (12 – x)(12 –x )

    160 – 8x – 20x + x2 = 144 – 12x – 12x + x2

    4x = 16

    x = 4

     

  • Question 3/10
    1 / -0

    Sum of the three consecutive number is 1956. What is 23% of the highest number ?

    Solutions

    Explanation :

    X+x+1+x+2 = 1956

    3x = 1956 – 3 = 1953

    X = 1953/3 = 651

    X+3 = 653

    23% of largest num = 23*653/100 = 150.19

     

  • Question 4/10
    1 / -0

    If the numerator of a fraction is increased by 100% and the denominator is increased by 200%. The resultant fraction is 1 (1/15), What was the original fraction ?

    Solutions

    Explanation :

    1(1/15) = 16/15

    X+x/y+2y = 16/15

    2x/3y = 16/15

    x/y = (16*3) / (15*2) = 8/5 = 1(3/5)

     

  • Question 5/10
    1 / -0

    Which of the following number is divisible by 11 ?

    Solutions

    Explanation :(9+3+4+7) – (2+4+5+1) = 11

     

  • Question 6/10
    1 / -0

    The sum of square of 2 number is 1972 and the difference of their square is 620. Find the number ?

    Solutions

    Explanation :

    X2+y2 = 1972

    X2 – y2 = 620

    Solve ths

    2x2 = 2592

    x2 = 1296

    x = 36

    y2 = 1972 – 1296

    y2 = 676

    y = 26

     

  • Question 7/10
    1 / -0

    Find the 5 digit number, 5th digit is one fourth of the 3rd digit and one half of the 4th digit. 3rd digit is one half of the 1st digit. 2nd digit is 5 more than the 5th digit.

    Solutions

    Explanation :

    5th digit – 1

    Second – 1+5 = 6

    Third = 4

    Four = 2

    First = 4*2 =8

     

  • Question 8/10
    1 / -0

    What is the no of zeroes at the end of the product of the no from1 to 100 ?

    Solutions

    Explanation :100/5 + 100/25 = 20+4 = 24

     

  • Question 9/10
    1 / -0

    x+y = 8  and x/y = 7 ,find y

    Solutions

    Explanation :

    7y+y = 4

    8y = 8

    Y = 1

     

  • Question 10/10
    1 / -0

    If three numbers are added in pairs, the sums equal to 11,16 and 23.Find the three numbers.

    Solutions

    Explanation :

    X+y = 11

    Y+z = 16

    Z+x = 23

    X+y+z = 25

    X = 25 – 16 = 9

    y = 25 – 23 = 2

    z = 25 – 11 = 14
