Question

The costs of two articles are in the ratio 7 : 4. If the cost of the first article is Rs. 2,800, find the cost of the second article.

Answer 1

Let cost of second article =x

cost of first article = 2800 Rs

Given 2800:x = 7:4

$\frac{2800}{x}=\frac{7}{4}$

$x=\frac{2800}{7}\times 4=1600Rs$

$\therefore$ cost of second article is 1600 Rs.
