If a number of which the half is greater than1/5th of the number by 15...
Solution:
Let's assume the number to be x.
Half of the number is x/2.
One-fifth of the number is x/5.
According to the given condition, the half of the number is greater than 1/5th of the number by 15.
So, we can write the equation as:
x/2 - x/5 = 15
To solve this equation, we need to find the common denominator and simplify the equation.
The common denominator for 2 and 5 is 10.
So, we can rewrite the equation as:
(5x - 2x)/10 = 15
Now, simplify the equation further:
3x/10 = 15
Multiply both sides of the equation by 10 to eliminate the fraction:
3x = 15 * 10
3x = 150
Divide both sides of the equation by 3 to solve for x:
x = 150/3
x = 50
Therefore, the number is 50.
Hence, the correct answer is option 'A' (50).
