How much money Meena have to pay? Correct Answer Rs. 320

Given Data:

Letter weight = 20 grams

Cost price = Rs.15

Calculation:

Price of 20 gram parcel = 15

One parcel weight is 310 grams

⇒ 60 grams + 5 × 50 grams

Price = 55 + 5 × 15

⇒ 55 + 74

⇒ Rs.130

The second Parcel weight is 460 grams

⇒ 60 grams + 8 × 50 grams

⇒ 55 + 8 × 15

⇒ 55 + 120

⇒ Rs. 175

Total price is = 15 + 130 + 175

⇒ Rs. 320

 ∴ The total price is Rs. 320
