Both segments representing education and rent respectively are each 10%.

Correct Option: C

Both segments representing education and rent respectively are each 10%. Hence, family's expenditure on these two items will be equal. i.e.. Rs. 375 will be expenditure on rent.

Here as per graph food expenditure, 40% = Rs. 750
⇒ 10% = 10 x 750/40 = Rs. 187.50

Correct Option: C

Here as per graph food expenditure , 40% = Rs. 750 per month
⇒ 10% = 10 x 750/40 = Rs. 187.50 per month
As per graph 10% is the expenditure on education.
∴ Annual expenditure (12 months) of the family on education = 187.50 x 12 = Rs. 2250

As per graph,
Expenditure on clothing = 20 % of total expenditure.

Correct Option: B

As per graph,
Expenditure on clothing = 20 %
Expenditure on clothing = Total expenditure x 20 %
Expenditure on clothing = 4500 x 20/100 = Rs. 900
Expenditure on clothing = 45 x 20 = Rs. 900

As per graph,
other expenses = 15 % of total expenditure.

Correct Option: B

As per graph,
other expenses = 15 % of total expenditure.
As we know that the angle made on center in a circle is 360°
Since 100% made an angle 360° in a circle.
therefore 1% made an angle 360° / 100 in a circle.
therefore 15% made an angle 15 x 360° / 100 in a circle.
Central angle for 15% =15 x 36° / 10
Central angle for 15% =3 x 36° / 2
Central angle for 15% =3 x 18° = 54°

As per graph
Expenditure on rent and clothing = 10% + 20% = 30%
Expenditure on medicine and other expenses = 5% + 15% = 20%

Correct Option: D

As per graph
Expenditure on rent and clothing = 10% + 20% = 30%
Expenditure on medicine and other expenses = 5% + 15% = 20%
∴ Ratio = 30% : 20% = 3 : 2
