  1. The percent profit when an article is sold for Rs. 78 is twice as when it is sold for Rs. 69. The C.P. of the article is ?
    1. Rs. 49
    2. Rs. 51
    3. Rs. 57
    4. Rs. 60
Correct Option: D

Let the C.P. be Rs. x
Then 2(69 - x) / 100 = (78 - x) / 100
⇒ 138 - 2x = 78 - x
⇒ x = 60
∴ C.P. = Rs. 60
