The cost of raw material of a product increases by 30, the manufacturing cost increases by 20 and the selling price of the product increases by 60. The raw material and the manufacturing cost, originally, formed 40 and 60 of the total cost respectively. If the original profit was one-fourth the original manufacturing cost, find the approximation new profit percentage.
Choose the correct answer
A) 48.38%
B) 54.68%
C) 62.48%
D) 42.36%
E) None of these
Explanation :   Let, the total initial cost of the product be Rs 100.   Manufacturing cost = Rs 60   Raw materials cost = Rs 40   Also, original selling price   =&gt; Rs100+(60/4)=

<output>115</output>
Rs 115.   New raw material cost=&gt;Rs 40+30% of 40= Rs 52.   New manufacturing cost   =&gt;Rs 60+20% of 60= Rs 72   New cost of the product = Rs124   New selling price   =&gt;115+60% of 115=Rs 184   New profit percentage   =&gt;60/124×100   =&gt;48.38%.   48.38%nswer : 48.38%
