Answer 1

Step-by-step explanation:

metre=50

cost=3725

------------------------------------------------

let take ‘n’ as metre

metre= n

cost 1788

formula of direct prop.= x1 upon y1 ; x2 upon y2.

= 50upon3725 ; N upon 1788

“then cross multiply each other”

3725N=89400

N=89400 upon 3725

= 89400 will cut from 3725 by 24

hence,we can purchase 24metre of cloth in 1788rupees
