Answer 1

Answer:

12 26/27

Yes, Sure

Step-by-step explanation:

L.C.M of 8 and 12 = ( 2×2×2×3) = 12.

Suppose that the Merchant buys 12 pens .

C.P. of 8 pens = ₹ 34.

C.P of 1 pen = ₹ (34/8).

C.P of 12 pens = ₹ ( 34/8× 12) = ₹ 54.

S.P of 12 pens = ₹ 57

S P of 1 pen =₹ (57/12).

S.P. of 12 pens = ₹ (57/12×12) =₹ 57

Since, S.P is greater than C.P, The merchant gains.

Gain = ( S.P - C.P ) = ₹ (57 - 50) =₹ 7.

Gain% = ( Gain / C.P × 100 ) %

= (7/54 × 100) %

= 350/27

= 12 26/27 Is your Answer.

Hope this helps you
