    Given that , C.P. of two articles = Rs. 520
    Suppose C.P. of article sold at loss = Rs. y.
    ∴ C.P. of article sold at profit = Rs. (520 – y)
    According to the question,

    y ×
    10
    = (520 – y) ×
    16
    100100

    ⇒ 5y = 520 × 8 – 8y
    ⇒ 13y = 520 × 8
    ⇒ y =
    520 × 8
    = Rs. 320

    Let the C.P. of article be Rs. y.
    According to the question,

    y × 105
    -
    y × 80
    = 200
    100100

    ⇒ 105y – 80y = 20000
    ⇒ 25y = 20000
    ⇒ y =
    20000
    = Rs. 800

    Using the given formula :
    Here, a = 20%, R = 200, b = 5%
    C.P. =
    R × 100
    b + a

    Using the given formula :
    Here, a = 20%, R = 200, b = 5%
    C.P. =
