A transistor is sold for Rs.350. If the sales tax accounts for 1/10 of this and profit is 1/5 of the remainder, find the cost price of the transistor.

Expert Answer

Selling price of transistor (SP) = Rs 350

Sales tax = 1/10 * SP = Rs 35

Remaining amount (RA) = Rs350-35 = Rs 315

Profit = 1/5*RA = Rs 63

Cost Price = RA - profit = Rs (315-63) = Rs 252
