Find the difference (in Rs.) between the amounts spent for A in 2013 and F in 2012?

A 3500

B 500    

C 1400

D 2600

E None of these

Solution

Correct Answer: Option C

∵ Total amount spent in 2013 = Rs. 40000

∵ Angular share of A in 2013 = 36o

∴ Amounts spent for A in 2013 \(= {\rm{\;}}\frac{{36}}{{360}} \times 40000 = {\rm{Rs}}.{\rm{\;}}4000\)

∵ Total amount spent in 2012 = Rs. 36000

∵ Angular share of F in 2012 = 54o

∴ Amount spent for F in 2012 \(= {\rm{\;}}\frac{{54}}{{360}} \times 36000 = {\rm{Rs}}.{\rm{\;}}5400\)

∴ Difference = 5400 – 4000 = Rs. 1400
