Answer 2

Answer:

Given

cost of pencil= rs 3

cost of pen= rs 1

to find: number of pens and pencils Amit bought for Rs 10

Explanation:

Let the number of pens he purchase = x

Let the number of pencils he purchase = y

So, according to the question,

3x + (1)y = 10

3x + y = 10

we can put diifferent values to satisfy this equation,

let y = 4

then 3x = 10-4

3x = 6

x = 2

so he purchased 2 pens and 4 pencils.
