    6.  Look  at  the  picture  given below. It shows a     8.  A, B and C are whole numbers such that
                         pattern made using matchsticks.                     A + B = C and:
                                                                                •  The value of B is five times the value of A.
                                                                                •  The value of B is greater than 15.
                         How many more matchsticks are there in the             •  The value of C is less than 30.
                         95th step than in the 79th step?                    What is the product of A and B.

                                       Two students Riya and Arjun bought some art supplies from different shops.
                                       They purchased some sketch pens and some notebooks. They represented their
                                       purchases using algebraic expressions:
                                          Riya: 6x + 3y
                                          Arjun: 4x + 5y

                                       where, x = number of packets of sketch pens and y = number of notebooks
                                       If each packet of sketch pens costs `20 and each notebook costs `40, what is
                                       the total cost of the combined items?
