Following Pie chart presents monthly expenditure by Sushma and Preeti in different heads. Sushma and Preeti make equal expenditure every month.

What is the ratio of central angles of expenditure on Education incurred by Sushma and Preeti?

Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. 1 : 1.

According to the given figures,

Expenditure of Sushma on education = 7200

Total expenditure by Sushma = 30,000 = Expenditure of Preeti

Now, central angle of expenditure on education for Sushma = ${7200 \over 30000} \times 360$ = 86.4

And central and of expenditure on education for Preeti = ${24 \over 100} \times 360$ = 86.4

The required ratio = 86.4 : 86.4 = 1 : 1

Hence the ratio of central angles of expenditure on Education incurred by Sushma and Preeti is 1 : 1.
