Answer 1

Given:-

• Rekha had Rs. 65. She bought some notebooks. The cost of each notebook is Rs 4⅓.

To Find:-

• How many notebooks did she buy?

Solution:-

Let the no. of notebooks of Rs 65. be x.

According to the question,

$:\implies$ 1 : 4⅓ = x : 65

$:\implies$1 : 13/3 = x : 65

$:\implies$1/(13/3) = x/65

$:\implies$3/13 = x/65

$:\implies$3(65) = x(13)

$:\implies$195 = 13x

$:\implies$195/13 = x

$:\implies$15 = x

$:\implies$x = 15

Hence, She bought 15 notebooks of Rs 65.
