Answer 1

Answer:

ஃ Rohit ( ₹ 27 ) got the pens cheaper than Mohit ( ₹ 30 ).

Step-by-step explanation:

By unitary method,

No. of pens Mohit bought = 15 pens

Cost of 15 pens = ₹ 450

Cost of one pen = 450 ÷ 15 = ₹ 30

In the same way,

No. of pens Rohit bought = 9 pens

Cost of 9 pens = ₹ 243

Cost of one pen = 243 ÷ 9 = ₹ 27

₹ 30 > ₹ 27

Mohit > Rohit

Answer 2

Answer:

Rohit got the pens cheaper

Step-by-step explanation:

Given:

Mohit purchases 15 pens for Rs.450

Mohit purchases 1 pen for Rs.450 / 15                 (total price / no. of pens)

                                           = Rs.30

Rohit purchases 9 pens for RS. 243

Rohit purchases 1 pen for RS.243 / 9              (total price / no.of pens)

                                        = Rs. 27

Price of 1pen which Mohit purchases >price of 1 pen which Rohit purchases
