As x 3. Two pens and a pencil cost Rs 32. A pen and a pencil cost Rs 20. Taking the price
of a pen as Rs p and the price of a pencil as Rs q, construct a pair of simultaneous
equations and by solving the pair find the price of a pen and the price of a pencil.
​

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.

The answer should be c.
