Question

चावल का मूल्य रुपए की kg 16 से बढ़कर रुपए की kg 18 होने पर इसकी खपत में कितनी % कमी करें ताकि इस पर खर्च अपरिवर्तित रहे​

Answer 1

Answer:

we know that Rate = use × expenditure

Step-by-step explanation:

Rate increased from 16₹/kg to 18₹/kg

and no change in expenditure

by formula we know that if no change in expenditure than Use and Rate will be inversely proportional

so,

rate. 16------18

use. 18------16

exp. 1 -------1

here we can see that use is decreased by 2kg from 18kg to 16kg so decreased percentage in use

use = (2/18)×100 = (1/9)×100 = 11.11%
