12% of 1200 + ? = 18% of 5400

• A. 654
• B. 676
• C. 828
• D. 538

Answer 1

Answer:

C. 828

Calculation:

Our given equation is 12% of 1200 + ? = 18% of 5400

⇒ $\frac{12}{100}\times{1200}$ + ? = 18/100 $\times$ 5400

⇒ 12 $\times$ 12 + ? = 18 $\times$ 54

⇒ 144 + ? = 972

⇒ ? = 972 – 144 

⇒ ? = 828

∴ The value of the given expression is 828.
