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

The pie chart given below shows the population of seven states L, M, N, O, P, Q and R. The total population of all these seven states is 225000. The population of a particular state is shown as a percentage of the total population of all these seven states to the total population of all these seven states. J1 = Sum of the population of state N and O J2 = Difference between the population of state M and N J3 = Average population of state M, N, O and P What is the value of (J1 + J2 + J3)? Correct Answer 142875

Given:

The per cent of the population in M = 32% of the total

The percentage of the population in N = 16% of the total

The percentage of the population in O = 14% of the total

The percentage of the population in P = 8% of the total

Concept:

1% = 225000/100 = 2250

Formula used:

Average = (The sum of all item)/(Total number of items)

Calculation:

⇒ J1 = (16 + 14) × 2250 = 30 × 2250 = 67500

⇒ J2 = (32 - 16) × 2250 = 16 × 2250 = 36000

⇒ J3 = {(32 + 16 + 14 + 8)/4} × 2250 = (70/4) × 2250 = 17.5 × 2250 = 39375

⇒ J1 + J2 + J3 = 67500 + 36000 + 39375 = 142875

∴ The required result will be 142875.
