S’s new income = (28000 – x)*112.5/100 K’s new income = x * 125/100 (28000 – x)*112.5/100 = x * 125/100 x = 12000 New Income of Shyama = 125% of 12000 = 15000

QUESTION: 20

500 kg of ore contained a certain amount of iron. After the first blast furnace process, 200 kg of slag containing 12.5% of iron was removed. The percentage of iron in the remaining ore was found to be 20% more than the percentage in the original ore. How many kg of iron were there in the original 500 kg ore?

Solution:

Initially ‘x’ kg of iron in 500 kg ore.

Iron in the 200 kg of removed =200*12.5/100= 25 kg.

The percentage of iron in the remaining ore was found to be 20% more than the percentage in the original ore

So (x-25)/300 = (120/100)*x/500

=> x – 25 = 18x/25

=> 7x = 625

=> x = 89.2
