Answer:

The CP of the pen = ₹77.8

The Loss percent is 10%

Step-by-step explanation:

SP of the pen = x – x/10 =70

x – x/10 = 70

9x/10 = 70

9x = 70× 10

x = 700/9 = ₹77.8

∴ The CP of the pen = ₹77.8

Loss = CP – SP

        = 77.8 – 70

        = 7.8 Loss %

        = (7.8 × 100) / 77.8

        =10.025% ≈ 10%

∴ The Loss percent is 10%
