A grocer buys 480 loaves of bread at ₹ 216 per dozen. He sold them at a gain of 15%. Find the selling price of 15 loaves of bread.

Answer 1

C.P. of 480/12 loaves of bread is 40*216= 8640
profit=15%
s.p.=(100+gain%)/100 * C.P.
       =100+15/100*8640
       =9936= s.p. of 480 loaves of bread 
       s.p. of 1 bread =20.7
s.p. of 15 bread =20.7*15= 310.5

Answer 2

The selling price of 15 bread loaves is ₹310.50.

Given:

• A grocer buys 480 loaves of bread at ₹216 per dozen.
• He sold them at a gain of 15%.

To find:

• Find the selling price of 15 loaves of bread.

Solution:

Formula to be used:

$\bf SP= CP\left(1+ \frac{P\%}{100} \right)$

Step 1:

Calculate the Cost price.

ATQ,

Cost price of 12 Bread loaves = ₹216

Number of dozens in 480 bread loaves$= \frac{480}{12}$

Thus,

Grocers buy 40 dozen bread loaves.

Cost price of 40 dozen bread loaves

$40 \times 216$

$= 8640$

Thus,

Cost price of 480 loaves is ₹8640/-.

Step 2:

Find the selling price.

Profit = 15%

$SP = 8640 \left(1 + \frac{15}{100} \right )$

$SP = 8640 \times \frac{115}{100}$

$\bf SP = 9936$

Thus,

Selling price of 480 bread loaves is ₹9936/-.

Step 3:

Find the selling price of 15 bread loaves.

SP of 480 bread loaves = 9936

SP of 1 bread loaf $= \frac{9936}{480}$

SP of 15 bread loaves $= \frac{9936}{480} \times 15$

SP of 15 bread loaves$\bf= 310.5$

Thus,

The selling price of 15 bread loaves is ₹310.50.
