vijay sells a pen at 25% loss and a pencil at 15% profit, he gets Rs.7 as profit.If he sells the pen at 25% profit and the pencil at 10% profit, he gets Rs 6 more. The price  of pen ?*1) 302) 403) 1004) 20

Let's denote the cost price of the pen as 'P' and the cost price of the pencil as 'Q'.

From the first condition, we know that Vijay sells the pen at a 25% loss and the pencil at a 15% profit, and he gets Rs.7 as profit. This can be written as:

0.75P + 1.15Q = P + Q + 7 ---- (equation 1)

From the second condition, we know that if he sells the pen at a 25% profit and the pencil at a 10% profit, he gets Rs 6 more. This can be written as:

1.25P + 1.10Q = P + Q + 7 + 6 ---- (equation 2)

Subtract equation 1 from equation 2, we get:

0.5P - 0.05Q = 6

Multiply by 20, we get:

10P - Q = 120 ---- (equation 3)

From equation 1, we can express Q in terms of P:

Q = 0.75P + 7 ---- (equation 4)

Substitute equation 4 into equation 3:

10P - (0.75P + 7) = 120

Solve for P:

P = 40

So, the cost price of the pen is Rs. 40. Therefore, the correct answer is 2) 40.
