Step-by-step explanation:

Let the consumption of sugar originally be 1 unit and let its cost be Rs 100.

Then, the new cost will be Rs130.

Now, Rs 130 will yeild ( 1/130 × 100 ) unit= 10/13 unit of sugar.

Then, reduction in consumption = ( 1 - 10/13 ) = 10/13 unit

Therefore, reduction % in consumption = ( 10/13 × 100 )%

= 76.92 %
