Answer:
Cost of 2 1/2 kg of potato = 30 rupees
Cost of one kg of potato =
= 2 1/2 = ( 2 × 2 ) + 1
= 2 1/2 = 5/2
= 2 1/2 kg = 5/2 kg
Cost of 1 kg of potato =
= 30/1 ÷ 5/2
= 30/1 × 2/5
= 60/5
We know that both 60 and 5 are divisible by 5 . So ,
= 60 ÷ 5 / 5 ÷ 5
= 12/1
= 12 rupees
Therefore , cost of 1 kg of potato will be 12 rupees .
