Show answer & explanation
Correct answer: C. z = 2x
Explanation
x% of y = xy/100 = 100, so xy = 10000. y% of z = yz/100 = 200, so yz = 20000. Dividing, (yz)/(xy) = z/x = 2, hence z = 2x.y का x% = xy/100 = 100, अतः xy = 10000। z का y% = yz/100 = 200, अतः yz = 20000। भाग देने पर (yz)/(xy) = z/x = 2, इसलिए z = 2x।More Mathematics & Numerical Ability questions
