Answer» Answer: Let the original cost PRICE (CP) be X. Selling price (SP) for Shyam (Shyam buying) =x(p100+1) where p is the profit percentage. Selling price for Mohan =x(p100+1)(p100+1) Selling price for RAKESH =x=(1−0.36)×x(p100+1)(p100+1) ⟹(p+100)2=100000.64 ⟹p+100=1000.8=125 ⟹p=25%

Answer:

Let the original cost PRICE (CP) be X.

Selling price (SP) for Shyam (Shyam buying) =x(p100+1) where p is the profit percentage.

Selling price for Mohan =x(p100+1)(p100+1)

Selling price for RAKESH =x=(1−0.36)×x(p100+1)(p100+1)

⟹(p+100)2=100000.64

⟹p+100=1000.8=125

⟹p=25%
