Answer 1

Answer:

1 envelope, Rs. 5000

Step-by-step explanation:

Cost of 15 envelopes = rs. 3750

No. of envelopes for rs 1  = 15/3750= 1 / 250

Total money = rs 300

no. of envelopes for rs. 300 = 1/250 *300

= 1 envelope( approximate )

Cost of 1 envelope = rs. 3750/15 = rs. 250

Cost of 20 envelopes = 20 * 250

= rs. 5000
