Answer 2

question:

the cost of 15 envelopes is rupees 37.50.How many envelopes can be bought for rupees 300.

solution:

$\purple{ \sf 120 }$

Given:

• 15 envelopes = ₹37.50

To find:

• ₹300 = how many envelopes?

step by step explanation:

$\sf \: let \: us \: do :$

$\implies \sf37.50 \ratio15 \ratio \ratio 300\ratio x$

$\boxed{\sf{product \: of \: means = product \: of \: extremes}}$

$\implies \sf37.50 \times x = 300 \times 15$

$\sf \implies x = \dfrac{300 \times 15}{37.50}$

$\sf \implies x = \dfrac{300 \times \cancel {15}}{ {\cancel {37.50}}}$

$\sf \implies x = \dfrac{300 \times 1}{2.5}$

$\sf \implies x = \dfrac{ \cancel{300} \times 1}{ \cancel{2.5}}$

$\sf \implies x = \dfrac{120 \times 1}{1}$

$\sf \implies x = 120$

Therefore:

$\red{ \sf 120 \: envelopes \: can \: be \: bought \: for \: rupees \: 300}$
