Answers:

1. 4;

Value of the item = Quantity × Price

Value of item B = 1500 kg × Rs.25 = Rs.37500 (1 quintal = 100 kg)

Value of item D = 1750 × 12.5 = 21875

Required ratio = 37500 : 21875 = 12 : 7

Shortcut : 15 × 25 : 17.5 × 12.5 = 12 : 7

2. 2;

Quantity sold by C after 20% increment = 120% of 2000 = 2400 kg

Price after 10% reduction = 90% of 27.5 = Rs.24.75

Value = 2400 × 24.75 = Rs.59400

3. 5;

Total value of E = 2500 × Rs.30 = Rs.75000

Total value of A = 2500 × 17.5 = Rs.43750

Required % = 75000/43750 × 100 = 171.43%

4. 1;

Average price = (25 + 12.5 + 15) /3 = 52.5/3 = Rs. 17.5

5. 3;

Total value of item C = 2000 × Rs.27.5 = Rs.55000

Total value of item F = 2250 × Rs.15 = Rs.33750

Difference = 55000 - 33750 = Rs.21250
