10 students can do a job for 8 days, but on the starting day, two of them inform that they’re not coming. by what fraction will the number of days required for doing the whole work get increased?

The correct answer is 10%

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
