Ans: $200
【make numerator same】
R - remaining
T - total
M - morning
A - afternoon
L - left
left → 1 - ⁷⁄₁₂ = ⁵⁄₁₂ R
left → ¼ T = ⁵⁄₂₀ T
20-12 = 8 units
【⁸⁄₂₀ = ⅖ 】 → morning
1 - ⁷⁄₁₂ = ⁵⁄₁₂
1 - ¼ ÷ ⁵⁄₁₂
= 1 - ⅗
= ⅖ → morning
afternoon sold #
$210÷$2 = 105
M : A : L : T
= 8 : 7 : 5 : 20
= 120 : 105 : 75 : 300
120÷6 = 20
20×$10 = $200 (Ans)
