Question

if the price of an article is increased by 15% and the total number of articles sold is decreased by 10% the increase in income is?​

Answer 1

Answer:

3.5%

Step-by-step explanation:

Let us say initially items are sold at Rs 100 per piece. Then sale of items 100 units

Revenue on sale Rs 100×100=10000

Now after 10% decrease new rate is Rs 90 per piece. 15% increase in sales. Means 115.

Revenue 90×115= Rs 10350.

For10000,increaseRs350.For10000,increaseRs350.

For 100 how much?

(100/10000)x350= 3.5% increase in revenue.
