Answer

D

Explanation

Let original cost price be CC. Original selling price S=1.4CS = 1.4C. New cost price = 0.6C0.6C. New selling price = S−5=1.4C−5S - 5 = 1.4C - 5.

Given new profit is 50%50\%: 1.4C−5=1.5×0.6C=0.9C1.4C - 5 = 1.5 \times 0.6C = 0.9C 0.5C=5  ⟹  C=100.5C = 5 \implies C = 10

Original selling price S=1.4×10=14S = 1.4 \times 10 = 14 rupees.
