Solution

The correct option is **D** 6

Cost of 1 hair clip = ₹ 3

Cost of 6 hair clips = 6 × ₹ 3

= ₹ 18 < ₹ 20

Cost of 7 hair clips = 7 × ₹ 3

= ₹ 21 > ₹ 20

So, she can buy only 6 hair clips for ₹ 18.

Cost of 1 hair clip = ₹ 3

Cost of 6 hair clips = 6 × ₹ 3

= ₹ 18 < ₹ 20

Cost of 7 hair clips = 7 × ₹ 3

= ₹ 21 > ₹ 20

So, she can buy only 6 hair clips for ₹ 18.
