Question

Ramesh went to a restaurant and ordered a coffee and a cookie for Rs 110. The coffee costs Rs 100 more than the cookie. What's the cost of the cookie?​

Answer 1

Answer:

Cost of cookie is Rs.5

Step-by-step explanation:

Let the cost of cookie be x

Then the cost of coffee is x+100

Total cost = 110 = x + x + 100

          2x + 100 = 110

                2x = 10

                  x = 5
