Heya!
Old price = Rs. 24
New price = Rs. 27
Increase in price = 27 - 24 = Rs. 3
That is, in %, = 3/24 × 100 = 25/2 %
Now, reduction in consumption
= (25/2)/(100+(25/2)) × 100
= 125/100 + 125 × 100
= 11.1 %
Hope it helps!

Does this fraction is correct ? Consumption decrease in fraction = (25/2) / (100+ (25/2)) × 100
Finally it comes as 100/9
I don't know, i just tried answering after searching for the formula in internet
It's okay thanku
