Answer 1

The number of pens purchase in Rs 156 is 39 pens  

Step-by-step explanation:

Given as :

The number of pens purchase = 15

The total cost of 15 pens = Rs 60

Let The number of pens purchase in Rs 156 = n pens

According to question

Applying unitary method

∵ In Rs 60 , total number of pens purchase = 15

So, In Rs 1 , total number of pens purchase = $\dfrac{15}{60}$

∴   In Rs 156 , total number of pens purchase = 156 × $\dfrac{15}{60}$

Or,                                                                         n = 156 × $\dfrac{1}{4}$

Or,                                                                         n = $\dfrac{156}{4}$

Or,                                                                          n  = 39

So, The number of pens purchase in Rs 156 = n = 39 pens

Hence, The number of pens purchase in Rs 156 is 39 pens   Answer
