CAT 1997 Question 10

Instructions

The graph given below shows the quantity of milk and food grains consumed annually along with female and male population (in millions). Use the data to answer the questions that follow.


Question 10

If one gallon milk contains 120 g of a particular nutrient and one tonne of foodgrains contains 80 g of the same nutrient, in which year was the availability of this nutrient maximum?

Solution

The maximum availability of the nutrient will be either in 1994 or 1995. because the cumulative production of milk and food grains is maximum in these years.

Availability in 1994 = (120*8) + (25*80) = 2960

Availability in 1995 = (6*120) + (31*80) = 3200

Hence the availability is maximum in 1995.
