    اسلام و علیکم میرے پیارے آئی ٹی دنیا کے دوستوں اور پیارے ممبرز اگر آپ کو حساب (میتھ) سے متعلق کوئی سوال پوچھنا ہو تو آپ مجھ سے پوچھ سکتے ہیں میں میتھ کا ایکسپرٹ ہوں کیونکہ میتھ میں ہمیشہ میرے +90 مارکس آتے ہیں اسکول میں بھی اور بورڈ کے امتحان میں بھی تو جس بھائی یا بہن کو میتھ میں کنفیوزن ہو وہ یہاں پر سوال پوسٹ کرسکتا/کرسکتی ہے
    شکریہ

    In a shop, the cost of 4 shirts, 4 pairs
    of trousers and 2 hats is $560. The
    cost of 9 shirts, 9 pairs of trousers
    and 6 hats is $1,290. What is the total
    cost of 1 shirt, 1 pair of trousers and
    1 hat?

    فرض کیجئے
    x : ایک شرٹ کی قیمت ہے
    y : ایک ٹراؤزر کے فئر کی قیمت ہے
    z : ایک ٹوپی کی قیمت ہے

    تو

    4x + 4y + 2z = 560 ------------> (a)
    9x + 9y + 6z = 1,290 ----------> (b)

    Equation (b) is Divide by 3 So.
    3x + 3y + 2z = 430 ------------> (c)

    Subtract Equation (c) into Equation (a) So.
    4x + 4y + 2z = 560
    -3x - 3y - 2z = -430
    --------------------
    x + y = 130 ------------------> (d)

    From Equation (c)
    3x + 3y + 2z = 430
    3 (x + y) + 2z = 430 ----------------> (f)

    Put the Value of (x+y) From Equation (d) into Equation (f)
    3 (130) + 2z = 430
    390 + 2z = 430
    2z = 430 - 390
    2z = 40
    z = 40/2
    z= 20

    So x+y+z = 130 + 20
    x+y+z = 150

    $150 تو ایک شرٹ ایک ٹراؤزر کا فئر اور ایک ٹوپی کی قیمت ہوئی

    Use log rule of product: log4(10) = log4(2) + log4(5)
    log4(2) = log4(41/2) = 1/2
    Use change of base formula to write: log4(5) = log8(5) / log8(4) = b / (2/3) , since log8(4) = 2/3
    log4(10) = log4(2) + log4(5) = (1 + 3b) / 2

    bhai ye question hal Karo
    درست جواب 4 ہوگا کیونکہ

    log_x (1/8) = -3/2
    => x^-3/2 = 1/8
    => x^3/2 = 8
    => x^1/2 = 2
    =>
    x = 4
