7. A shopkeeper buys 300 identical articles a tota

sashaice [31]

Step-by-step explanation and answers:

300 articles at a total cost of $1500:

$1500 / 300 = $5 / article

Sells 260 articles at a price 20% above this ^ price:

20% of $5 is $1, so $5 + $1 = $6

Then he sells 260 articles at the price of ^ $6

260 * $6 = $1560

Each of the remaining articles is sold at a price that's 50% of the 260 he sold.

He sold those for $6, so he would now sell the last 40 for $3

From the remaining 40 articles, he makes 40 * $3, or $120

The shopkeeper made $1560 + $120 = $1680, which is $180 more than he bought them for ($1500)

Therefore, he made a profit percentage of $180 / $1500, (the amount of profit over the amount spent).

He made a profit percentage, compared to the cost price, of 12%.

Answer:

<h2>Option B:</h2><h3>112 families </h3>

Step-by-step explanation:

Given,

No. of families = 75

Out of 75 no. of families had cars = 42

Out of 1, no. of families can have cars

$= \frac{42}{75}$

Therefore, 

Out of 200 families, no. of families had cars

$= 200 \times \frac{42}{75}$

$=200 \times \frac{14}{25}$

= 8 × 14

= 112

Hence, 

option B is correct as 112 families have cars out of 200 families (Ans)
