Nawab’s satisfaction/ utility level is given by adding twice of the satisfaction level of Saif with the satisfaction level of Amir.
Saif makes a profit of ? 100, his satisfaction level goes up by 10% and if he suffers a loss of ?100, his satisfaction level goes down by
10%.
Amir makes profit of ? 100, his satisfaction level goes up by 5% and if he suffers a loss of ? 100, his satisfaction level goes down by
15%.
Nawab’s satisfaction level is 24 and the satisfaction level of Saif is the same as the satisfaction level of Amir
Let x be the satisfaction level of Saif
24=3x
x=8
If Saif makes a profit of 100 and Amir suffers a loss of ? 100, the satisfaction level of Saif and Amir goes up by 10% and goes down by
15% respectively.
The satisfaction of Saif and Amir = 8.8 and 6.8
Nawab's new satisfaction/ utility level = 2*8.8+6.8 =24.4
Percentage change =
=1.67%
D is the correct answer.
