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.

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?
(a) 200x + 320y (b) 200x + 400y
(c) 240x + 320y (d) 240x + 400y
