60 percent off 1300

60% off 1,300 is 520

1,300 minus 60 percent off is 520

The discount itself is 780: 1,300 × 60 ÷ 100 = 780. Taking it off 1,300 leaves 520.

Only approximately: 520 ÷ 0.4 = 1,300. The discount is rounded to the cent, so several prices give the same 520 — 1,299.99 (discount 779.99), 1,300 (discount 780) and 1,300.01 (discount 780.01); the paid price alone cannot tell them apart.
