उत्तर

a. Every 60 posters, Anju’s class students raise = ₹ 250

So, from 1 poster, Anju’s class students raise = `250/60` = ₹ `25/6`

If Anju's sell 102 posters, then they raise

= `25/6 xx 102`

= 17 × 25

= ₹ 425

Hence, Anju’s class make ₹ 425 by selling of 102 posters.

b. Since, by selling 1 poster, Anju’s class raise = ₹ `25/6`

For raise exactly ₹ 2000, they needs to sell

= `2000 + 25/6`

= `2000 xx 6/25`

= 480 posters
