Answer 2

Calculation of 33% of 125 and its increase by itself

To find 33% of a number, we multiply the number by 0.33. In this case, we want to find 33% of 125.

33% of 125 = 0.33 * 125 = 41.25

Next, we need to increase this number by itself.

41.25 + 41.25 = 82.5

Therefore, the number obtained by finding 33% of 125 and increasing it by itself is 82.5.

Calculation of the difference between three-fourths of the obtained sum and 25% of the same sum

To find three-fourths of a number, we multiply the number by 0.75. In this case, we want to find three-fourths of 82.5.

Three-fourths of 82.5 = 0.75 * 82.5 = 61.875

Next, we need to find 25% of the same sum.

25% of 82.5 = 0.25 * 82.5 = 20.625

Now, we can calculate the difference between three-fourths of the obtained sum and 25% of the same sum.

Difference = Three-fourths of the obtained sum - 25% of the same sum = 61.875 - 20.625 = 41.25

Therefore, the difference between three-fourths of the obtained sum and 25% of the same sum is 41.25.

Comparison with 50% of 125

Now, let's compare the calculated difference with 50% of 125.

50% of 125 = 0.5 * 125 = 62.5

The calculated difference (41.25) is not equal to 50% of 125 (62.5). Therefore, the statement that the difference between three-fourths of the obtained sum and 25% of the same sum is equal to 50% of 125 is not true.

Conclusion

In conclusion, the statement that the difference between three-fourths of the obtained sum and 25% of the same sum is equal to 50% of 125 is false. The calculated difference is 41.25, which is not equal to 50% of 125.
