Question

The production of rice in the year 2001 was
1000 tonnes which was 25% of the total food grain
production in that year. In the next year if the
production of rice decreased by 4% and production of
rice as a percentage of total food grain production
increased by 5 percentage points, what is the total
food grain production in 2002? (in tonnes)​

Answer 1

Answer:

Let total food grain production in year y

Then we have

TFGP for 2001=1000

1/4TFGP=1000=>TFGP=4000

In 2002 the equation becomes

3/10TFGP=960 so

TFGP=3200

so answer is 3200
