Correct Answer - Option 3 : 3 ∶ 5
Given:
Loss % of Marry = 25%
Profit % of John = 25%
Formula used:
In case of Loss, S.P = [(100 - Loss%)/100] × C.P
In case of Profit, S.P = [(100 + Profit%)/100] × C.P
Calculation:
Let the C.P of both articles be x.
According to the first condition,
S.P1 = [(100 - 25)/100] × x
⇒ 3x/4
According to the second condition,
S.P2 = [(100 + 25)/100] × x
⇒ 5x/4
According to the question,
(S.P1/S.P2) = [(3x/4)/(5x/4)]
⇒ 3 ∶ 5
∴ The required ratio is 3 ∶ 5.
