Question

A man wants to replace the flooring of his room with two types of tiles.He spent Rs 1410on 12Type A tiles and 11type B tiles.If the price of three type of Btiles is the same as one Type A tile,find a cost of one tile of each type

Answer 1

Let Suppose

Price of  B tile is : X              
Price of A tile is 3X

Now Calculate : X(11) + 3X(12)= 1410
 
11X + 36X = 1410
47X =1410
X= 1410/47
X=30
Now ! Substitute the value in Price Equation

Price of  B tile is : 30 
Price of A tile is : 90
