Step-by-step explanation:

let x be the marked price

for 15% discount Ram gains Rs 100.

x \times  \frac{15}{100}

is the discount

let y is price without any profit

x - y = 400

eq 1

x - x \times  \frac{15}{100}  - y = 100

 \frac{17}{20} x -  \frac{20}{20} y = 100

17x - 20y = 2000

eq 2

from eq1

x = 400 + y

substitute x value in eq 2

17(400 + y) - 20y = 2000

 - 3y = 2000 - 6800

y = 4800 \div 3

y = 1600

x = 400 + y

x = 400 + 1600

x = 2000

Therefore marked price is Rs. 2000
