Question

If due to 10% decrease in the price of sugar, Ram can buy 5 kg more sugar in Rs. 100, then find actual price of sugar.​

Answer 1

Answer:Let the old price of sugar be Rs x/kg

Rs x = 1kg

Rs 100 = 100/x

After 10 percent decrease in price , price becomes = x - (10/100)*x = x - x/10 = Rs (9x/10) / kg

Now Rs 9x/10 = 1kg

Rs 100 = (10/9x) * 100 = 1000/9x

acc to ques , 1000/9x = 100/x + 5

=>1000/9x = (100 + 5x) / x

=>1000/9 = 100 + 5x

=>1000/9 - 100 = 5x

=>100/9 = 5x

=> x = 20/9
