Question

s The present price of a ceiling fan is 5670. If its value decreases every year by 10%, then find its value before 2 years.class8​

Answer 1

Answer:

7000

Step-by-step explanation:

Let previous year's price be x

Present price of ceiling fan = 5670

A. T. Q

x-10℅of x = 5670

x-1/10 of x = 5670

10x/10-1/10x= 5670

10x-1x/10x=5670

9x/10=5670

9x=5670*10 (Cross multiplication)

9x=56700

x=56700/9

x=6300

Price before 1 year = 6300

Now, we have to find the price before 2 years

x-10%of x =6300

x-1/10 of x =6300

10x-1x/10 = 6300

9x/10= 6300

9x=6300*10

9x=63000

x=7000

Hence, the price before 2 years is 7000
