Step-by-step explanation:

cost of 10 pencils = Rs 60

cost of 1 pencil is = 60 ÷ 10 = 6

cost of 40 pencil is = 6 × 40 = 240

Answer:

If we need to find cost of 40 pencils we need to find 1 pencil cost.

So, 60 ÷ 10 = 6

Hence, 1 Pencil cost is 6 .

As we get 1 pencil cost we need to multiply 40 with cost of 1 pencil

So, 40 × 6 = 240

Therefore, 40 pencils cost for 240 rupees.
