Step-by-step explanation:
Given Cost of 3 1/2 kg of rice is ₹69 1/2 then find the cost of 5 kg rice
- This can be solved by unitary method. So we have
- 3 1/2 kg of rice costs Rs 69 1/2
- Or we can write this as
- 7/2 kg of rice costs Rs 139/2
- So 1 kg of rice will cost 139/2 / 7/2
- = 139 / 7
- = Rs 19.85
- Now 1 kg rice costs Rs 19.85
- Therefore 5 kg of rice will cost 19.85 x 5
- = Rs 99.28
- Or
- 3.5 kg of rice costs Rs 69.5
- So 5 kg of rice will cost 69.5 x 5 / 3.5
- = Rs 99.28
