Coffee cups are purchased by K in following quantities: 3 cups for Rs. 40 and 5 cups for Rs. 60. If K sells all the cups at the rate of 3 cups for Rs. 50, how much gain or loss % is incurred by K? Correct Answer 33.33%
Given:
CP of 3 cups = Rs. 40
CP of other 5 cups = Rs. 60
SP of 3 cups = Rs. 50
Concept used:
Gain % = (Profit/C.P.) × 100
Gain = S.P – C.P
Calculation:
Total CP of 8 cups = Rs. (40 + 60) = Rs. 100
S.P. of 8 cups = Rs. (50/3) × 8
⇒ Rs. 400/3
⇒ Gain = Rs.
⇒ Rs. 100/3
⇒ Gain% = × 100%
⇒ 100/3% = 33.33%
∴ K incurred a gain of 33.33%
