How long will Machine Y, working alone, take to produce x candles? | |
I. | Machine X produces x candles in 5 minutes. |
II. | Machine X and Machine Y working at the same time produce x candles in 2 minutes. |
Answer: Option
Explanation:
I. gives, Machine X produces | x | candles in 1 min. |
5 |
II. gives, Machine X and Y produce | x | candles in 1 min. |
2 |
From I and II, Y produces | ![]() |
x | - | x | ![]() |
= | 3x | candles in 1 min. |
2 | 5 | 10 |
3x | candles are produced by Y in 1 min. |
10 |
x candles will be produced by Y in | ![]() |
10 | x x | ![]() |
min = | 10 | min. |
3x | 3 |
Thus, I and II both are necessary to get the answer.
Correct answer is (E).

3x/10 candles are produced by y in 1min,
i.e: y produces 3x/10 candles in 1min,
i.e 3x/10 = 1,
3x = 10,
x = 10/3,
Therefore, x candles will be produced by y in 10/3 mins.

@Srikanth.
Because 3x/10 candles are produced by y in 1min.
so, 3x/10 candles = 1 min.
ie it takes y to produce x candles in 3/10 min.
y produces x candles = 3/10 min.
Because 3x/10 candles are produced by y in 1min.
so, 3x/10 candles = 1 min.

y produces x candles = 3/10 min.
