Question

One hundred offices need to be painted. The workers choose between yellow, blue, or red paint. They decide that 45% of the offices will be painted yellow; 28% will be painted blue, and the remaining offices will be painted red. What amount of offices will be painted red?

Answer 1

27 offices will be painted red.

Explanation:

Yellow offices:

= 45% of 100 offices

= 0.45 × 100

= 45 yellow offices

Blue offices:

= 28% of 100 offices

= 0.28 × 100

= 28 blue offices

Red offices:

= Total number of offices - yellow offices - blue offices

= 100 - 45 - 28

= 55 - 28

= 27 red offices

Therefore, 27 offices will be painted red.

Answer 2

• 27 offices will be painted red

-------------------------------------------------

Out of 100 offices:

• 45% of the offices will be painted yellow ⇒ 45 offices
• 28% of the offices will be painted blue ⇒ 28 offices

Remaining offices will be painted red:

• 100 - (45 + 28) =
• 100 - 73 =
• 27
