Answer 2

Answer: 1056

Step-by-step explanation:

• Given: Difference between 40% and 28% of a number is 198.
• To find: 64% of the number.
• Solution:

        Let the number be x.

According to question,

     $\frac{40x}{100} -\frac{28x}{100}=198$

 ⇒ $\frac{12x}{100} =198$

 ⇒ $x=\frac{198*100}{12}$

 ⇒ $x=66*25$

 ∴ x=1650.

Now, 64% of 1650

       = $\frac{64}{100}*1650$

       = 1056.

• Hence, the required answer is 1056.
