Question 1191764
The ratio of the profit, cost of materials and labour in the production of an article is 5:7:13 respectively.
let x = the multiplier
then actual value$
5x = profit
7x = cost
13x = labor
 If the cost of materials is Le 840 more than that of labour,
7x = 13x + 840
right here you can tell something wrong with this problem
labor has to be more than cost

 find the total cost of producing the article.
