Answer 1

Answer:

Let C.P of instrument =Rs.100

Profit =25% of Rs.100=Rs.25

If profit is Rs.25,C.P=Rs.100

∴ If profit is Rs.150,

C.P=Rs.25100×150=Rs.600

S.P of the instrument =Rs.600+Rs.150=Rs.750

Let M.P of the instrument be Rs. 100

If S.P is Rs.80, M.P=Rs.80100×750=Rs.937.50

Thus, marked price of the instrument =Rs.937.50
