Solution

Let's solve this step by step:

  1. Let's assume the initial cost of Jowar is 100 units. So, after a 12% increase, the new cost becomes 112 units.

  2. Now, let's assume the initial consumption is also 100 units. So, the initial expenditure is 100 (cost) * 100 (consumption) = 10,000 units.

  3. The problem states that the expenditure is increased by 40%. So, the new expenditure becomes 10,000 (initial expenditure) + 40/100 * 10,000 (increase) = 14,000 units.

  4. Now, we need to find out the new consumption such that the expenditure is 14,000 units. We know that expenditure = cost * consumption. So, 14,000 (expenditure) = 112 (cost) * new consumption.

  5. Solving the above equation, we get new consumption = 14,000 / 112 = 125 units.

  6. So, the consumption has to be increased from 100 units to 125 units. The percentage increase in consumption = (125 - 100) / 100 * 100 = 25%.

So, the correct answer is 25%.
