Question

If the duty on an article be reduced by 40 percent of its price then by how musch percent the consumption of that article be increased so that the revenue is increased by 10 percent ?


I CANNOT UNDERSTAND THE CONCEPT OF CONSUMPTION AND REVENUE SO PLS EXPLAIN THAT. I WILL MARK BRAINLIEST TO THEM

​

Answer 1

Let initial rate was 100

Now, 40% decrement in duty,

rate = 100−40=60

To make their revenue 100, consumption must be increase of 40.

So, % increment =

60

(40×100) = 200/3 %

but here revenue is increased by 10%

so,we have to add 10% in increment

$200 \div 3 + 10 \div 100 \times 200 \div 3 = 210 \div 3$

200/3+10%of200/3

200/3+10/100×200/3

200/3+20/3

220/3

so the answer is 200/3

Answer 2

Answer:

200/3

Step-by-step explanation:

Let initial rate was 100

Now,40% decrement in duty,

rate=100-40=60

To make their revenue 100, consumption must be increase of 40.

So,%increment=40/60*100

=200/3%
