Answer 1

Find the cost of 1 kg:

10 kg = Rs 61  (Given)

1 kg = 61 ÷ 10 = Rs 6.10

Find the cost of 15kg:

1 kg = Rs 6.10

15 kg = 6.10 x 15 = Rs 91.50

Find the amount of wheat Rs 1 can buy:

Rs 61 = 10 kg (Given)

Rs 1 = 10 ÷ 61 = 10/61 kg

Find the amount of wheat Rs 122 can buy:

Rs 1 = 10/61 kg

Rs 122 = 10/61 x 122 = 20 kg

Answer: (a) Rs 91.50 (b) 20 kg
