Question

the cost of a book is rs25 more than twice the cost of a geometry box .find the cost of the book if the total cost is rs130

Answer 1

Answer:

let the cost of geometry box be x

∴cost of book be 2x +25

A/Q, x+2x+25=130

       ⇒3x+25=130

         ⇒3x=130-25

          ⇒x=105/3

           ⇒x=35

∴cost of geometry box =RS 35

and cost of book=2×35+25

                            =RS 95
