If 90% of A =30% of B and B=x% of A, then the value of x is?a)800b)300...
Let's solve the given problem step by step:
1. Given that 90% of A is equal to 30% of B.
- Mathematically, this can be written as: 0.9A = 0.3B
2. We also know that B is equal to x% of A.
- Mathematically, this can be written as: B = (x/100)A
To find the value of x, we can substitute the second equation into the first equation:
0.9A = 0.3[(x/100)A]
Now let's solve for x:
0.9A = 0.3(x/100)A
Divide both sides of the equation by A:
0.9 = 0.3(x/100)
Multiply both sides of the equation by 100 to get rid of the fraction:
90 = 0.3x
Divide both sides of the equation by 0.3:
x = 90/0.3
x = 300
Therefore, the value of x is 300.
Hence, the correct answer is option B) 300.
