In The Above Question
Given Data
The price of commodity X increases by 40 paise per year
the price of commodityY increases by 15 paise every year.
In 2001 Year The Prices Of Commodity X and Y are 4.20 and 6.30
Given Question Is "in which year commodity X will cost 40 paise more than the commodity Y ?"
Let Us Consider A Be The Year At Which The Commodity Of X Will cost 40 pause more than the community Y
A Part From That Data Converted In To The Mathematical Form
Then
X=4.20+0.4 A And Y=6.30+0.15 A
Now You Have To Find Out The Year At Satisfied Given Condition Then
X-Y=0.4
4.20+0.4 A-(6.30+0.15 A) =0.4
-2.1+0.25A=0.4
0.25 A=0.4+2.1=2.5
A=2.5/0.25
A=10
That Means After 10 Years The Required Condition Satisfied
2011 Is The Required Year In Which The Given Condition Satisfies
