Answer 2

Given,

The sum of a number and its 3/8 is equal to 5/6 of 39.6

To find,

Square of that number.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

Let, the number = x

(Assume x as a variable to do the further mathematical calculations.)

According to the data mentioned in the question,

x + 3x/8 = 5/6 × 396/10

11x/8 = 66/2

x = 66/2 × 8/11

x = 6×4

x = 24

Square of that number = 24×24 = 576

Hence, the square of that number is 576
