Question

How much should a man reduce the use of milk whose price has increased by 25% su that he may have to
spend no extra money.​

Answer 1

Answer:

Step-by-step explanation:

Ans is 12%.

If price is increased by 25% then reduction in consumption should be 25/(100+25)*100 = 20 % (without increasing the cost)

It means initially consumption was 100, now it is 100-20=80. Now expense is incresed by 10% on current consumption means 80+10% of 80=80+8=88

Now the consumption is reduced by 100-88=12
