answer is 5

Answer 2

Answer:

The girl initially wished to buy 5 flowers

Step-by-step explanation:

Cost m roses = Rs. n

Cost of (m+10) roses = Rs. 2

As mentioned in the questions, m and n are integers; hence n<2; n=1

As per condition:

$\frac{m}{100} +\frac{(m+10)}{200} = \frac{12}{80}$

$\frac{2m+m+10}{200} =\frac{12}{80}$

$\frac{3m+10}{200} =\frac{12}{80}$

$3m+10=30$

$3m=20\\\\m=5$

Hence the girl initially wished to buy 5 flowers
