SSC CGL Previous Year Math Questions: 2
58. A, B, C and D purchase a gift worth 60. A pays 1/2 of what others are paying, B pays 1/3 of what others are paying and C pays 1/4 of what others are paying. What is the amount paid by D ?
Option A : 16
Option B : 13

Firstly, we express every fraction in decimal form.
4/5 = 0.8 , 7/8 = 0.875
6/7 = 0.857
5/6 = 0.833 = 0.83
So , 4/5 < 5/6 < 6/7 < 7/8
