Question

Answer 1

Answer:

Rs 1200 & 1920

Step-by-step explanation:

Let say cost price of 1 fan = C

cost price of 2nd Fan = 3120 -C

Profit on 1 Fan = (36/100) * C =  36C/100

Selling Price of 1 Fan = C + 36C/100 =  136C/100

Loos on 2nd Fan = (15/100)* (3120-C) = 15 * (3120-C) / 100

Selling Price of 2nd = (3120-C)   -  15*(3120-C)/100 = 85*(3120-C)/100

136C/100 = 85*(3120-C)/100

136C = 265200 - 85C

221C = 265200

C = 265200/221

C = 1200

cost price of 1 Fan = 1200

Cost price of 2nd Fan = 3120-1200= 1920
