Answer:
Total amount received by Mrs Khanna will be 182.5 Rs.
Step-by-step explanation:
Cost of the potatoes = 25 Rs per kg
Cost of [tex]2\frac{1}{2}[/tex] kg potatoes = Weight of the potatoes × Per kg cost of the potatoes
= 2.5 × 25
= 62.5 Rs
Cost of onions = 30 Rs per kg
Cost of 3 kg onions = 3 × 30
= 90 Rs
Per kg cost of Peas = 70 Rs
Cost of [tex]1\frac{1}{2}[/tex] kg Peas = 1.5 × 70
= 105 Rs
Per kg cost of Carrots = 40 Rs
Cost of [tex]1\frac{1}{2}[/tex] kg Carrots = 1.5 × 40
= 60 Rs
Total amount of the vegetables = 62.5 + 90 + 105 + 60
= 317.5 Rs
Since she gave a note of 500 Rs
Balance amount she got = 500 - 317.5
= 182.5 Rs
Therefore, total amount received by Mrs Khanna will be 182.5 Rs.
