Answer 1

Answer:

1620

Step-by-step explanation:

Given:-

A number, 1500.

The number is increased by 20 %.

Then the number is decreased by 10 %.

To find:-

The number after changing it value.

Solution:-

Increasing the number by 20 %

1500 + (1500 × 20/100)

1500 + (15 × 20)

1500 + 300

1800

Decreasing the number by 10 %

1800 - (1800 × 10/100)

1800 - (18 × 10)

1800 - 180

1620

Hence, the number after changing the values is 1620.
