Final answer:
After calculating the expression (602/495) * (1 + 20%), the result is approximately 1.46, which does not match any of the given multiple-choice options (A) 1.44, (B) 1.28, (C) 1.38, (D) 1.36. It seems there may be an error in the calculation or the options provided.
Step-by-step explanation:
The simplified form of the expression (602/495) * (1 + 20%) first involves calculating the percentage increase and then multiplying this by the fraction. A 20% increase adds 0.20 to 1, resulting in 1.20. To find the simplified form, we multiply the fraction 602/495 by 1.20. This gives us:
(602/495) * 1.20 = 1.215151515... * 1.20
After carrying out the multiplication, we get 1.458181818... which we can round to 1.46. However, this result does not match any of the provided options (A) 1.44, (B) 1.28, (C) 1.38, (D) 1.36. Therefore, we must review the calculations to ensure there hasn't been any mistake, as the result obtained, 1.46, isn't listed.
