​

Answer 1

Step-by-step explanation:

The value decreases by 10% hence now the value will be 90% of 36000.

$\frac{90}{100} \times 36000$

= 32400 rupees

Now the value increases by 20% thus the value will be 120% of 32400.

$\frac{120}{100} \times 32400$

= 38880 rupees

Answer 2

Step-by-step explanation:

the value decreased by 10%

now the value will be 90% of 36000

90/100×36000

32400

now the value increased by 20%

the value will be 120% of 32400

120/100×32400

38880
