1. (5): (900 + 700 + 300 + 650 + 550)/5 = 3300/5 → Avg. = 660

2. (4): a =600 /900 →66%

3. (5): Avg. of Exp. = (600 + 300 + 150 + 450 + 350)/5 → Avg. = 370
Avg. of income = (900 + 700 + 300 + 850 + 550)/5 → Avg. = 660
Total sum = 370 + 660 → 1030

4. (4): Total exp. Of A + B + C = 600 + 300 + 150 →1050
Total income of C + D + E = 300 + 850 + 550 →1700
∴ (1050/1700)x100 →61.76→62 approx.

5. (5): D + A income = 850 + 550 → 1400 
Total expenditure =(1400/1850) →28 : 37

6. (5): Both the statements are needed.

7. (3): Either of the statements is sufficient.
