A) 6:31 | B) 11:30 |

C) 7:30 | D) 31:6 |

Explanation:

Since S.P. = 5 (M.P. - S.P.) => 5 M.P. = 6 S.P.

M.P. = (6/5) S.P.

Since the percentage discount = Percentage profit,

$\frac{{\displaystyle \frac{\mathbf{6}}{\mathbf{5}}\mathbf{S}\mathbf{.}\mathbf{P}\mathbf{}\mathbf{-}\mathbf{}\mathbf{S}\mathbf{.}\mathbf{P}}}{{\displaystyle \frac{\mathbf{6}}{\mathbf{5}}\mathbf{S}\mathbf{.}\mathbf{P}}}\mathbf{\times}\mathbf{100}\mathbf{}\mathbf{=}\mathbf{}\frac{\mathbf{S}\mathbf{.}\mathbf{P}\mathbf{}\mathbf{-}\mathbf{C}\mathbf{.}\mathbf{P}}{\mathbf{C}\mathbf{.}\mathbf{P}}\mathbf{\times}\mathbf{100}$

Therefore, 1/6 = (S.P/C.P) – 1 => S.P = (7/6) C.P

M.P = 6/5 S.P = 6/5 x 7/6 C.P = 7/5 C.P

Therefore, Ratio of discount to C.P

= (M.P – S.P)/C.P = [{(7/5)C.P - (7/6)C.P} / C.P.]

= 7/30

Therefore, the ratio is 7 : 30
