If the monthly saving of the family is Rs. 4500, then the monthly income of the family is:

  1. A.

    Rs. 45000

  2. B.

    Rs. 30000

  3. C.

    Rs. 25000

  4. D.

    Rs. 20000

Answer

B

Explanation

Total percentage in a pie chart = 100%. Percentage for Savings (F) = 100%−(20%+15%+18%+20%+12%)=100%−85%=15%100\% - (20\% + 15\% + 18\% + 20\% + 12\%) = 100\% - 85\% = 15\%.

Let total monthly income be II. 15% of I=4500  ⟹  0.15×I=4500  ⟹  I=3000015\% \text{ of } I = 4500 \implies 0.15 \times I = 4500 \implies I = 30000

Monthly income = Rs. 30,000.
