|
Answer» Given that the COST of 35 envelopes is RS 105. Cost of 35 envelopes = Rs 105 Cost of ( 35 / 35 ) envelopes = Rs ( 105 / 35 ) Cost of 1 envelope = Rs 105 / 35 Cost of 1 envelope = Rs 3 Cost of ( 1 / 3 ) envelope = Rs ( 3 / 3 ) ∴ Cost of 1 / 3 envelope = Rs 1 ∴ Cost of 1 / 3 x 90 envelopes = Rs 1 x 90 ⇒ Cost of 30 envelopes = Rs 90 Therefore, 30 envelopes can be BROUGHT for Rs 90. |
