Answer 1

Answer:

15percent of 680

15/100*680

so 15percent is 102

Step-by-step explanation:

now the rice he buy is of 680-102

rate 578

now in that 102 he can buy more 6kg rice

so per kg rice 102/6

so price is 17per kg

he buys now 40kg rice

before he buy 40-6 is 34 kg rice

before the price was 680/34

rate 20 per kg

so per kg 3 rupee decreased
