Question

If 4 dozen eggs cost ₹ 144, find the cost of 5 scores of eggs [1 score = 20]

• A. 450
• B. 250
• C. 300
• D. 360

Answer 1

The correct option is C

300

More the number of eggs, more the cost .
Hence it is in direct proportion.
We know that, 4 dozen = 4 $\times$ 12 = 48
Given, 1 score = 20
$\therefore$ 5 scores = 5 $\times$ 20 = 100
Hence 144 $\times$ 100 = 48 $\times$ $x$

$⟹x=\frac{144\times 100}{48}$

$⟹x=₹300$
