Answer 2

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
