Let the age of Rakesh = x
Let the age of Mohan = y
Let the age of Shyam = z
we know,
x = 10% of y
⇒x = ¹⁰/₁₀₀ * y
⇒x = y/10 (equation 1)
Also,
x = 20% of z
⇒x = ²⁰/₁₀₀ * z
⇒x = z/5 (equation 2)
Therefore by equations 1 and 2,
y/10 = z/5
⇒y/2 = z
⇒y = 2*z
Therefore, y is equal to twice of z i.e.
y = 200 % of z
Let the age of Mohan = y
Let the age of Shyam = z
we know,
x = 10% of y
⇒x = ¹⁰/₁₀₀ * y
⇒x = y/10 (equation 1)
Also,
x = 20% of z
⇒x = ²⁰/₁₀₀ * z
⇒x = z/5 (equation 2)
Therefore by equations 1 and 2,
y/10 = z/5
⇒y/2 = z
⇒y = 2*z
Therefore, y is equal to twice of z i.e.
y = 200 % of z
