Solution

Quantity of wheat that can be purchased from Rs 30.50 = 5kg

Applying unitary method, where firstly we find the value of one unit and then the value of required number of units.

From Rs 1, quantity of wheat that can be purchased = 530.50kg

From Rs 61, quantity of wheat that can be purchased

= 530.50×61 = 53050×61×100kg [multiplying numerator and denominator by 100]

= 10kg

Thus, we can purchase 10kg wheat from Rs 61
