Answer 2

For 7 kilograms of onion we have to pay ₹280.

Given data :

The price of the 17 kilograms of onion in the given rate is ₹680.

• At first we have to calculate the rate price of the onion.

(Rate price is the price of single unit of substance,eg. ₹ x/kg)

• To calculate the rate we have to use the following mathematical formula :

= Total substance/Total price

= 680/17

= ₹40/kg

• So,the rate price will be ₹40 per kilogram of onion.

• Now,we have to calculate the price of 7 kilograms of onion

• 1 kilogram of onion cost = ₹ 40

7 kilograms of onion cost = 40×7 = ₹280

• So,the price of 7 kilograms of onion is ₹280. (answer)
