Question

If M% of x is y and N% of y is x, then:
1. \(\frac{M}{N} = 100\)
2. \(\frac{N}{M} = 100\)
3. MN = 10000
4. M + N = 100

Answer 1

Correct Answer - Option 3 : MN = 10000

Given:

M% of x = y

N% of y = x

Calculation:

Substituting the value of y in second equation,

N% of (M% of x) = x

⇒ (N/100) × (M/100) × x = x

⇒ N × M = 10,000

∴ The relation NM = 10,000 is the solution.
