Question

Rehana went to the market and saw that price of dal of 1kg is rs 20 and the price of the rice of 1 kg is rs 40 less than that of fish of 1kg. The quantity of fish and that of the dal in rs 240 is equal to the quantity of the rice in rs 280. Let us calculate the cost price of 1kg fish.

Answer 1

The Price of dal rs 20

And price of rice rs 40

Dal and fish both rs 240 (240-dal price(20)=220

Dal+rice+fish= total 280 already we know rice and dal price so total -dal and rice price. Eg 280 -20 and 40 (60)=220 is fish price

Simple method - dal 20+ rice 40=60

280-60=220 fish price is 220
