Question for Practice Questions Level 2: Percentage - 1
Try yourself:If p, q, r and s are four numbers such that q is 20% more than p, r is 25% less than q, s is 40% more than r, and s is k% higher than p, then what is the value of k?
Explanation
Let p = 100
q = 100 + 20% of 100 = 120
r = 120 - 25% of 120 = 120 - 30 = 90
s = 90 + 40% of 90 = 90 + 36 = 126
s - p = 126 - 100 = 26
So, s is 26 higher than p.
Required percentage = (26/100) × 100% = 26%
