Answer» Correct Answer - Option 1 : 38 kg

Given:

Weight of statue = 160 kg

Copper = 50%

Zinc = 25%

Removed aluminium = 5%

Calculations:

Percentage of aluminium in statue = [100 – (50 + 25)]% = 25%

Weight of statue = 160 kg

Quantity of aluminium = 25% of 160 kg

⇒ (25/100) × 160

⇒ 40 kg

According to the question,

⇒ 40 - (40)× 5%

⇒ 38 kg

∴ The quantity of aluminium requires to make the statue is 38 kg.
