Question

Pinku bought notebooks at the rate of 4 rupees 35 and sold them at the rate of 5 rupees 50 find the number of notebooks should he sell to earn a profit of 171 rupees​

Answer 1

Step-by-step explanation:

C. P of notebook=4 rupees 35 paise

S. P of notebook=5 rupees 50 paise

Profit by selling 1notebook=C.P-S.P

=5+50/100 - 4+35/100

= 5+0.5 - 4+0.35

=5.5 - 4.35

=1.15

No. of notebooks that can be bought by profit of 1.15 rupees= 1

No. of notebooks that can be bought by profit of 171 rupees= 171/1.15=17100/115

= 148.695

= 148 notebooks

Therefore, 148 notebooks can be sold to earn profit of Rs.171
