PYQs Based Test - 20 : General Aptitude

Two finance companies P and Q, declared fixed annual rates of interest on the amounts invested with them. The rates of interest offered by these companies may differ from year to year. Year-wise annual rates of interest offered by these companies are shown by the line graph provided below.



If the amounts invested in the companies, P and Q, in 2006 are in the ratio 8:9, then the amounts

received after one year as interests from companies P and Q would be in the ratio:

Which of the following function(s) in an accurate description of the graph for the range(s) indicated?



i) y = 2x + 4 for -3 ≤ x ≤ -1

ii) y = |x - 1| for -1 ≤ x ≤ 2

iii) y = ||x| - 1| for -1 ≤ x ≤ 2

iv) y = 1 for 2 ≤ x ≤ 3
