$\bigstar \: He \: has \: \underline{ \: \sf \green{\bf{ 18 \: two \: rupee \: coin}} \: } .$

Given:

Step-by-step explanation:

Let no.of 1 rupee coin be x

Let no.of 2 rupee coin be y.

y = 11 + x

Given that, he has eleven more rupees 2 coins than rupees 1.

$x + y = 25$

$\implies x + 11 + x = 25$

$\implies 2x + 11 = 25$

$\implies 2x = 14$

$\implies \boxed{x = 7}$

∴ He has 7 one rupee coin .

$2 \: rupee \: coin = 11 + x$

$\implies \: y = 11 + 7$

$\implies \: \boxed{y = 18}$

∴ He has 18 two rupee coin .

Verification:

$x + y = 25$

$\implies \: 7 + 11 = 25$

$\implies \: \boxed{25 = 25}$
