Answer 2

Question:−

$\sf\small{\green{\:A \:dealer \:purchased \:250\: bulbs\: for\: Rs.10\: each.}}$

$\sf\small{\green{\: However\: 12 \:bulbs\: got\: fused \:which \:he \:had\: to\: throw\: away.}}$

$\sf\small{\green{\:He\: sold\: the\: remaining\: bulbs\: at\: Rs.12\: each.}}$

$\sf\small{\green{\:Find \:the \:gain \:or\: loss\: percent\: in\: the\: dealing.}}$

$\sf\bold{\blue{Answer:-}}$

Gain%=14.24

$\sf\small{\pink{Step-by-step:-}}$

$\sf\small{\red{Given:-}}$

Cost of each bulb is Rs. 10.

Total number of bulbs purchased by dealer is 250.

Number of fused bulbs is 12.

Selling price of remaining bulbs is Rs. 12 each .

$\sf\small{\red{\:To\:Find:-}}$

Gain or loss percent made by the dealer?

$\sf\small{\red{Solution:-}}$

Let's find out the total cost of 250 bulbs.

→Cost of 250 bulbs = Rs. 10

→250 bulbs =10×250

$\sf\small{\green{\: Total\:cost=Rs. 2500}}$

Now, 12 bulbs got fused

Remaining bulbs= 250 - 12 = 238

$\sf\small{\red{\:According \:to\: question:-}}$

Selling price of 238 bulbs is Rs. 12 each.

Total S. P of 238 bulbs = 12×238

$\sf\small{\green{\:Total\: S. P \:= 2856}}$

Here, S. P >C.P so dealer made a profit.

$\sf\small{\pink{★Profit=S.P-C.P}}$

Profit = 2856-2500

$\sf\small{\green{Profit = 356}}$

$★Gain percent =\frac{Gain}{CP}×100$

$→\frac{356}{2500}×100$

$→\frac{356}{25}$

→14.24%

Hence, dealer made 14.24% profit in dealing.
