In a loom at Goplanagar 14 weavers can weave 210 sarees in 12 days. The workshop got an order to supply 300 sarees within 10days during the Pujas. Let’s work out using the method of the Rule of Three how many extra weavers have to be employed to complete the work in time.

theorem1:-


The Rule of Three is a Mathematical Rule that allows you to solve problems based on proportions. By having three numbers: a, b, c,


(a)Direct proportions rule of 3:-


if ab


c then


(b)inverse proportions rule of 3:-


if ab


c then


formula:- (i)direct method----


(ii)indirect or inverse proportions xy=k



given:- method used is called indirect or inverse proportions method



s1=210,s2=200,w1=14,d1=12,d2=10,w1=?





w2 =24


that mean 24-14=10 more people are required.
