The pie chart given below shows the population of seven states L, M, N, O, P, Q and R. Total population of all these seven states is 225000. Population of a particular state is shown as a percent of total population of all these seven states. J1 = Sum of population of states N and O J2 = Difference between population of state M and N J3 = Average population of states M, N, O and P What is the value of (J1 + J2 + J3)?

Show answer & explanation
Correct answer: B
First, convert the percentage distribution of each relevant state into absolute population values (Total = 225,000):
State M: 32% of 225,000 = 72,000
State N: 16% of 225,000 = 36,000
State O: 14% of 225,000 = 31,500
State P: 8% of 225,000 = 18,000
Next, calculate the variables:
J1 (Sum of N and O): 36,000 + 31,500 = 67,500
J2 (Difference between M and N): 72,000 - 36,000 = 36,000
J3 (Average of M, N, O, and P): (72,000 + 36,000 + 31,500 + 18,000) / 4 = 157,500 / 4 = 39,375
Finally, sum the variables:
J1 + J2 + J3 = 67,500 + 36,000 + 39,375 = 142,875
