Solution
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
