Question

7. The cost of a pen is Rs 5.50. Anjum has Rs 15 with her. How many pens can she buy with this
money ​

Answer 1

Let anjum can buy "a" no. of pens with this money

15 = 5.5×a

$a = \frac{15}{5.5}$

a= 2.72

but the pen can't be fraction

hence she can buy maximum 3 pen

Answer 2

Cost of 1 pen = ₹5.50

Total money with Anjum = ₹15

${\sf{No.\: of\: pens\: she\: can\: buy\: =\: {\dfrac{15}{5.50}}}}$

= 2.72 pens

Therefore, 2.72 pens can be bought.
