Question
If 35 is the mean proportional of 25 and x, then what is
value of x?Solution
To find the value of x, we use the concept of mean proportional. Given that 35 is the mean proportional of 25 and 2, we have: 35 = √25 × x  Square both sides 352 = 25 × x 1225 = 25x X=1225/25 =49 So, the value of x is 49.
