The pie chart given below shows the number of banks in 5 cities. The data is presented in the terms of percent. Difference between the total number of banks in N and Q and total number of banks in L and M = 2500.
What is the ratio of the number of banks in N to the total number of banks in P and Q?
Show answer & explanation
Correct answer: A
Explanation
Given:
P = 15%, Q = 25%, L = 10%, M = 20%, N = 30%
(N + Q) − (L + M) = 2500
(N + Q) = 30 + 25 = 55%
(L + M) = 10 + 20 = 30%
Difference = 55% − 30% = 25%
25% = 2500
100% = 10000
N = 30% = 3000
(P + Q) = 15% + 25% = 40% = 4000
Ratio = 3000 : 4000 = 3 : 4
