    Find the cost price, if : (i) S.P. = Rs. 1,680 and profit = 12% (ii) S.P. = Rs. 1,128 and loss = 6% (i) S.P. = Rs. 1,680 and profit = 12% (ii) S.P. = Rs. 1,128 and loss = 6%
    Ans : (i) S.P. = Rs. 1, 128, Profit = 12%
    C.P. = 100/(100 + profit) × S.P.
    ∴ C.P. = 100/(100 + 12) × 1680
    = (100 × 1680)/112
    = (25 × 1680)/28
    = 25 × 60
    = Rs. 1500 (ii) S.P. = Rs. 1,128, Loss = 6%
    C.P. = 100/(100 - Loss) × S.P.
    ∴ C.P. = (100 × 1128)/(100 - 6)
    = (100 × 1128)/94
    = 100 × 12
    = Rs. 1200 (i) S.P. = Rs. 1, 128, Profit = 12%
    C.P. = 100/(100 + profit) × S.P.
    ∴ C.P. = 100/(100 + 12) × 1680
    = (100 × 1680)/112
    = (25 × 1680)/28
    = 25 × 60
    = Rs. 1500 (ii) S.P. = Rs. 1,128, Loss = 6%
    C.P. = 100/(100 - Loss) × S.P.
    ∴ C.P. = (100 × 1128)/(100 - 6)
    = (100 × 1128)/94
    = 100 × 12
    = Rs. 1200
  • #2-i
    S.P. = Rs. 1,680 and profit = 12%
    Ans : S.P. = Rs. 1, 128, Profit = 12%
    C.P. = 100/(100 + profit) × S.P.
    ∴ C.P. = 100/(100 + 12) × 1680
    = (100 × 1680)/112
    = (25 × 1680)/28
    = 25 × 60
    = Rs. 1500
  • #2-ii
    S.P. = Rs. 1,128 and loss = 6%
    Ans : S.P. = Rs. 1,128, Loss = 6%
    C.P. = 100/(100 - Loss) × S.P.
    ∴ C.P. = (100 × 1128)/(100 - 6)
    = (100 × 1128)/94
    = 100 × 12
    = Rs. 1200
