Question:
Profit selling 10 candles equals selling price of 3 bulbs. While loss on selling 10 bulbs equal selling price of 4 candles. Also profit percentage equals to the loss percentage and cost of a candle is half of the cost of a bulb. What is the ratio of selling price of candles to the selling price of a bulb?

Option A):
3:2
Option B):
3:4
Option C):
4:5
Option D):
5:4

Correct Answer is Option A):
3:2

Explanation:
Price    Candle    Bulb
SP    A(let)    C(let)
CP    B    D

and, C = 2A
Profit = 10 (B-A) = 3D
Loss = 10 (C-D) = 4B
Profit % = (3D*100)/10A
Loss % = (4B*100)/10C
Now, By the questions,
(3D*100)/10A = (4B*100)/10C
B/D = 3/2.
