Question

after making 25 pair of trouses from a length if cloth 1.25 m of cloth is left if 1.15m of cloth is required for each pair of trouses what was the initial length if the cloth ?

Answer 1

if 1.15m. cloth is required for one trouser then for 25 trousers it is 25×1.15
so let x is the initial length of cloth and remaining cloth is 1.125
so the equation may be written as-
25×1.15 = x-1.25
115/4 = x-1.25
so x=30 m.
hope it will helps u
