Question

Cost of 105 envelopes is Rs. 350. How many envelopes can be purchased for Rs. 100?

Answer 1

In Rs. 350, the number of envelopes that can be purchased = 105.

Therefore, in Rs. 1, number of envelopes that can be purchased = `105/350`

Therefore, in Rs. 100, the number of envelopes that can be purchased

= `105/350 × 100 = 30`.

Thus, 30 envelopes can be purchased for Rs. 100.
