If x% of a is the same as y% of b, then z% of b will be :
Answer & Solution
Correct Answer:
Option
B
According to the question,
a × $$\frac{x}{100}$$ = b × $$\frac{y}{100}$$
xa = yb
⇒ b = $$\frac{xa}{y}$$
Put value of b in given equation,
z% of b = z% of $$\frac{xa}{y}$$ = $$\frac{zx}{y}$$ of a
a × $$\frac{x}{100}$$ = b × $$\frac{y}{100}$$
xa = yb
⇒ b = $$\frac{xa}{y}$$
Put value of b in given equation,
z% of b = z% of $$\frac{xa}{y}$$ = $$\frac{zx}{y}$$ of a
