• Cost price ( C.P) = ?

Let cost price be "x",

Substitute these values in the given formula,

$\implies \sf{135 = \big(1 + \frac{8}{100} \big) (x)} \\ \\ \implies \sf{ 135 = \frac{27}{25} (x)} \\ \\ \implies \sf{x \: = \frac{135 \times 25}{27} } \\ \\ \implies \: \sf{ x = \frac{3375}{27} } \\ \\ \implies \boxed{\sf{x \: = 125}}$

hence ,cost price is ₹125 .
