If increasing 50 by x% is equal to the result of decreasing 70 by x%. what is the value of x?

Increasing 50 by x% can be written as:

.................(1)

Decreasing 70 by x % can be represented by the expression:

...........(2)

Now we are given in the question that if we increase 50 by x% and 70 by x%, then the two values are equal.

so equating (1) and (2) , we get

bringing 0.01x to the left side:

taking 50 to the right side, subtracting it from 70

dividing both sides by 0.02

Answer x=2000

answer: 1) twenty-seven times y
