Question

in making a radio set the cost of labour and materials are in the ratio of 3:2. A manufacturer sells a set for tk 150 to make a gain of 25% on the cost. what is the cost of the materials for the set?​

Answer 1

Answer:

simple manufacturer is selling on 25% profit that means cost price+25%profit(125%)=150₹

& if 125% =150₹

then 100% is = 150×100/125=120₹

100%(cost price)=120₹

& Cost price = cost of labour/cost of material=3/2

cost of material=2/5×120=48₹
