Question

A vendor buys lemons at Rs 25 per dozen ands sells them at the rate of 5 for Rs 12. Find his gain on loss per cent.

Answer 1

$\Huge\mathfrak{Solution}$

$<b>$Given

Cost price of per dozen(12) lemons = Rs. 25

Selling price of 5 lemons = Rs. 12

So the selling price of 1 lemon = Rs(12/5)

Now the selling price of 12 lemons = Rs. (12/5 × 12)

= Rs.28.8

Since Selling price (SP) > Cost price (CP)

So it's a gain

Gain = (SP - CP)

Gain = Rs.(28.8 - 25)

Gain = Rs. 3.8

$Gain \: percent = (\dfrac{gain}{cp} \times 100)\%$

substituting the values we have

$(\frac{3.8}{25} \times 100)\% \\ \\ = 15.2\%$

Thanks

Have a colossal day ahead

Answer 2

CP of 12(dozen) lemons = 25

CP of 1 lemon = 25/12

SP of 5 lemons = 12

SP of 1 Lemnon = 12/5

25/12  or 125/60      ∠       12/5 or 144/60

CP ∠ SP

So gain

144/60   -   125/60  = 19/60

Profit/ CP   x 100  = profit percent

19/60 ÷ 125/60   x 100  = 19/125 x 100 = 15.2 %

So he gained by 15.2%
