We are told that 10% of all imported widgets are made of brass and of those, 20% are green and 40% are red. Since we know that there are only three colors, the remaining 40% must be blue. 40% blue of 10% brass widgets leads to 4% blue brass widgets out of the total 10,550 widgets.

10,500 /100 * 4 = 420. Answer A.

brass widgets B = 10500 * 10/100 = 1050
Brass widgets painted blue = 100 - 20- 40 = 40%

i.e 40% of 1050 = 420

Ans A

Answer = A. 420

Brass widgets $$= \frac{10}{100} * 10500 = 1050$$

Of these, 20% green & 40% red.

Remaining blue $$= 100-(20+40) = \frac{40}{100} * 1050 = 420$$

Since 10% are made of brass - 1050.
Of these 20% are green and 40% are red. So 40% are blue.

So blue brass = 40% of 1050 = 40*1050/100 = 420.

OFFICIAL SOLUTION:

(A) Question asks for the number of brass widgets painted blue.

First, determine the number of widgets that are brass:
(0.1)(10,500) = 1,050

Next, determine the percentage of brass widgets that are painted blue: 100% – 20% green – 40% red = 40% blue

Finally, determine the number of brass widgets painted blue: (0.4)(1,050) = 420

Given : 10% of the Widgets are made of Brass of those 20% are colored green and another 40% are colored red

100 - 20 - 40 = 40%

40 % of 10% of 10500 = required

$$\frac{40}{100} * \frac{10}{100} * 10500$$

4 * 105 = 420
