Question

The pie diagrams on the monthly expenditure of two families $A$ and $B$ are drawn with radii of two circle taken i the ratio $16:9$ to compare their expenditures.

• A. $Rs16,000$ and $Rs9,000$
• B. $Rs8,000$ and $Rs4,500$
• C. $Rs25,600$ and $Rs8,100$
• D. $Rs4,000$ and $Rs3,000$

Answer 1

Answer: (A)

$Rs16,000$ and $Rs9,000$

Given,

Let the ratio of their circles be $16x$ and $9x$.

The total income of $A$ and $B$ is $25000$

$⟹16x+9x=25000⟹25x=25000⟹x=1000$

Their expenditures are $16x,9x=16\times 1000,9\times 1000$

$=16000,9000$

Tha expenditure of A and B are $Rs.16000$ and $Rs.9000$
