Question

D) Decrease 500 ml by 25% and then increase by 10%.​

Answer 1

Answer: 412.5 ml

Explanation:

500 ( 1 - 25%) ( 1 + 10%)

= 412.5 ml

Answer 2

412.5 ml

Explanation:

To decrease 500 ml by 25%, you would need to multiply 500 by 0.25 to find the amount of decrease:

• 500 × 0.25 = 125 ml

Subtract that amount from the original value:

• 500 - 125 = 375 ml.

Therefore decreasing 500 ml by 25% would give us 375 ml.

To then increase this value by 10%, you would multiply it by 0.10 to find the amount of increase:

• 375 × 0.10 = 37.5 ml

Now, add that amount to the previous value:

• 375 + 37.5 = 412.5 ml.

Therefore, if you decrease 500 ml by 25% and then increase it by 10%, the final result is 412.5 ml.
