Explanation:

Let's solve it step by step:

- Let the price of each pen be Rs P and each pencil be Rs Q.

- Total cost: 10P + 8Q = 200 ...(1)

- Alternate option: 5P + 24Q = 200 ...(2)

- Let's solve these two equations.

Multiply (2) by 2:

- 10P + 48Q = 400

Now subtract (1) from this:

- (10P + 48Q) - (10P + 8Q) = 400 - 200

- 40Q = 200

- Q = 5

Substitute Q = 5 in (1):

- 10P + 8*5 = 200

- 10P + 40 = 200

- 10P = 160

- P = 16

Now, reviewing options:

- Option 1: Rs 16

- Option 2: Rs 15

- Option 3: Rs 14

- Option 4: Rs 13

Correct Answer: Option 1 - Rs 16
