The cost of an article (which is composed of raw materials and wages) was 3 times the value of raw materials used. The cost of raw materials increased in the ratio 3 : 7 and wages increased in the ratio 4 : 9. Find the present cost of the article if its original cost was Rs. 18. Choose the correct choice from the following choices:
A) Rs. 41
B) Rs. 30
C) Rs. 40
D) Rs. 46
E) Rs. 56
Assume the raw materials’ cost as Rs.150, then the total cost will be Rs. 450, (Thus, wages cost is Rs. 300)   Since, the cost of raw materials goes up in the ratio of 3 : 7, the new raw material cost would become Rs. 350   The new wages cost would be in the ratio 4 : 9 as Rs. 675.   The new total cost would become, Rs. 1025.   Since Rs 450 become Rs. 1025 (change in total cost),   Unitary method calculation would give us that Rs. 18 would become Rs. 41.   Rs. 41NSWER:Rs. 41
