(3)625
(4) 590​

Answer 1

Answer:

Let its CP be x then its SP is 1.25x.

When CP is increased by 20 it becomes (x+20)and when SP is increased by 4 it becomes (1.25x +4). In this case SP becomes 1.15 of CP ( given).

New Equation:1.15 (x+20)= 1.25x+4

1.15x +23 = 1.25x + 4

0.10x = 19. Therefore x=190

Hence CP of the articleis Rs.190/-.
