Question

1. The selling price of 16 spoons is equal to the cost price of 15 spoons. Find the loss percent.
2. On selling an exhaust fan for Rs. 7350, a man gains 1/6 of its cost price. Find the cost price of the fan.
3. If the manufacturer gains 10%, the wholesale dealer 15%, and the retailer 25% then what is the production cost of a washing machine whose retail price is Rs.37950?​

Answer 1

Answer:

Step-by-step explanation:

1. Given,

S.P. of 16 spoons = C.P of 15 spoons.

Loss = C.P. - S.P. = 16-15 = 1 spoon.

Loss % = Loss/C.P. * 100 = 1/16*100 = 100/16 = 6.25% = Loss Percent.

2. S.P. of Exhaust Fan = ₹7350.

A Man Gains = 1/6*C.P.

Let C.P. Be 'x'.

Therefore,Gain = 1/6*x = x/6.

C.P. = S.P. -Gain

x = 7350-x/6

x + x/6 = 7350.

6x+x / 6 = 7350.

7x / 6 = 7350.

7x = 7350*6

x = 7350*6/7  = 1050*6 = ₹6300.

3.Given,

Retail price of machine = 37950.

Manufacturer gains 10%

Wholesaler gain = 15%

Retailer gain = 25%

Let the cost of production of an electric toaster be = x

Hence 125% of 115% of 110% of x = 37950

= 125 / 100 × 115/100 × 110/ 100 × x = 37950

= 37950 × 1000000 / 125 × 115 × 110

= 24000

Therefore, the cost of machine is 24000.
