Question

Mr. Jones sold two pipes at $1.20 each. Based on the cost, his profit one was 20% and his loss on the other was 20%. On the sale of the pipes, he:

(a) broke even, (b) lost 4 cents, (c) gained 4 cents, (d) lost 10 cents, (e) gained 10 cents

Answer 1

Answer:

20 % profit on $ 1.20

= $ 20/100 × 1.20

= $ 0.20 × 1.20

= $ 0.24

Similarly, 20 % loss on $ 1.20

= $ 20/100 × 1.20

= $ 0.20 × 1.20

= $ 0.24

Therefore, in one pipe his profit is $ 0.24 and in the other pipe his loss is $ 0.24.

Since both profit and loss amount is same so, it’s broke even.

Answer: (a)

Answer 2

Answer:

$20\% \: profit \: on \: 1.20 \\ = > 20 |100 \times 1.20 \\ = > 0.24 \\ = \geqslant 20\% \: loss \: on \: \: 1.20 \\ = \leqslant 20 |100 \times 1.20 \\ = \leqslant 0.24 \\ = \geqslant profit = 0.24 \\ = \geqslant loss = 0.24 \\ = \leqslant both \: are \: same \: it \: was \: they \: are \: broken \\ = \leqslant answer \: is \geqslant = \\ = \leqslant \beta \geqslant =$
