If one side of a square is increased by 35%, by what percentage another side is reduced so that its area remains same?
Answer & explanation
Correct answer: option 1
Area = Side1 × Side2
*(When area is constant, then the relation b/w sides are inversely proportional)
Side1 : 20 : 27
Side2 : 27 : 20
Side2 should be reduced by = 27 - 20 = 7
So, Reduce percent = \(\frac{7}{27}\) × 100 = 25\(\frac{25}{27}\)%
