A is 25% more than B and B is 40% less than C. If C is 30% more than D, then by what percent is A less than D?
2.5
Let the value of D be 100x
value of C = 100x × (130/100) = 130x
value of B = 130x × (60/100) = 78x
value of A = 78x × (125/100) = 97.5x
A is less than D by = 100x – 97.5x = 2.5x
A is less than D by (in %) = (2.5x/100x) × 100 = 2.5%Important Questions from Percentage
