in the ratio 7:4. If the cost of
the first article is 3500, find
the cost of the second article.

Answer 1

Answer:

Ratio in the cost of two articles = 7 : 4

Cost of first article = Rs. 2800

Let cost of the second article = x

7 : 4 = 2800 : x

---->7/4=2800/x

---->7×x=2800×4

---->x=2800×4/7

---->x=1600

therefore the cost of second article is 1600
