Question

At a fruit shop 2 1/4 kg of apple cost ₹90. At this rate what is the cost of 750 gm of apple

Answer 1

Answer:

Cost of 9/4 kg = Rs.90

Cost of 1 kg = 90 ÷ 9/4 = 90 × 4/9 = Rs.40

750 gm = 3/4 kg

Hence, cost of 750 gm = 40 × 3/4 = Rs.30

Answer 2

cost of rs 9/4 kg = 90

cost of 1 kg = 90 ÷ 9/4 = 90 × 1/4 = RS 40

750 gm = 3/4 kg
