Question

if Rained 90 me this year,while it was 120 mm, last year. Hence there was _______% decrease in the rains.​

Answer 1

Answer:

Step-by-step explanation:

Here total decrease = Rain in previous years - Rain in this year

= 120 - 90 mm = 30 mm.

Therefore, decrease percentage = Total decrease/Rain in previous year × 100.

= 30÷120×100

= 100÷4

= 25%

Therefore, decrease percentage = 25%.
