Answer 2

Answer:

Q. 9 = 2 notes of 20 Rs + 1 note of 10 Rs + 3 notes of 5 Rs

= 2 × 20 Rs + 1 × 10 Rs + 3 × 5 Rs

= 40 Rs + 10 Rs + 15 Rs

= 65 Rs

Q. 10 = Cost of 1 ball is 7 Rs + 1 Notebook is 10 Rs + 1 Pencil is 5 Rs

So, Cost of 2 Balls and 2 pencils = 2 × 7 Rs + 2 × 5 Rs

= 14 Rs + 10 Rs

= 24 Rs
