$<i>It is given that 15 envelopes cost ₹45.</i>$



$\bold{Therefore \: cost \: of \: 1 \: envelope = \: \frac{45}{15} } \\ \\ \\ which \: is \: equal \: to \: \cancel\frac{45}{15} = 3$



$So \: the \: cost \: of \: 20 \: such \: envelopes \\ \\ \\ = Cost \: of \: 1 \: envelope \times Number \: of \: envelopes$



$= > Rs. 3 \times 20 \\ \\ \\ = > Rs. 60$



$\boxed{\boxed{Hence \: your \: answer \: is \: Rs. 60.}}$
