and 4 pencils is 96. Find the cost of each pen.

(prefers step by step answer)

Answer 1

Step-by-step explanation:

Let the cost of each pen and pencil be `p` and `q` respectively.

16p + 8q = 352 --- (1)

4p + 4q = 96

8p + 8q = 192 --- (2)

(1) - (2) 8p = 160

p = 20

therefore cost of each pen is Rs. 20

Answer 2

Answer:

Rs.10

Step-by-step explanation:

4 pencil = 96

1 pencil = 24

96 × 2 = 192

352-192 = 160

160 ÷ 16 = 10
