Question

is 20% more than B,B is 25% more than C,C is 60% less than D and D is 20% more than E. Based on the above information, which of the following is true?​

Answer 1

Step-by-step explanation:

A is 30% more than B.

So, A = B + 30% of B = B + 30/100 *B = B + 3/10 *B = 13/10 *B

B is 60% less than C.

So, B = C - 60% of C = C - 60/100 *C = C - 3/5 *C = 2/5 *C

So, A = (13/10)*(2/5)*C = 13/25 *C.

So, we get C > A.

The difference: C - A = C - 13/25 *C = 12/25 *C

Hence, the percentage by which A is less than C = (C-A)/C *100 = 12/25 *100 = 48%.
