Question

the price of rice increased from Rs15 by 15% and then reduced by 30 paise. what was the net increase

Answer 1

after increasing 15% price is= 115/100×15=17.25rs
reducing 30 paisa= 17.25-.30=16.95
net increase is (16.95_15)/15×100=13%

Answer 2

Original Price = Rs15

Find the price after 15% increase:

Increase = 15% x 15 = 0.15 x 15 = Rs 2.25

Price after increase = 15 + 2.25 = Rs 17.25

Find the price after it is reduced by 30 paise:

30 Paise = Rs 0.30

Price after decrease = 17.25 - 0.30 = Rs 16.95

Find the net increase:

Net increase = 16.95 - 15 = Rs 1.95

Find the net increase percentage:

Net Increase Percentage = 1.95/15 x 100 = 13%

Answer: There was a net increase of Rs 1.95 and that increase is 13%
