Question

the cost of a book is rupees 25 more than twice the cost of a geometry box find the cost of the book if the total cost is rupees 130

Answer 1

Cost of geometry =35rs
cost of book=2*35+25=95 rs..

Answer 2

Answer:

95 Rs.

Step-by-step explanation:

according to the question X is for because we don't know the cost of book 25 means 25 more than the cost of geometry box and 2x means twice the cost of a geometry box so

X + 25 + 2 X =130

3X(2x+1x)=130-25 (transposing)

x=105/3=35

cost of geometry box is equals to 35 now we have to find out the cost of book so

2*35(geometry box cost) +25

70(25*35)+25

=95

so the answer is 95 Rs.
