The students of Anju's class sold posters to raise money. Anju wanted to create a ratio for finding the amount of money her class would make for different numbers of posters sold. She knew they could raise Rs. 250 for every 60 posters sold. |
(a) How much money would Anju's class make for selling 102 posters? |
(b) Could Anju's class raise exactly T 2,000? If so, how many posters would they need to sell? |
Answer:
Here, Anju?s class raised money for every 60 posters. (a) Let x be the money.
Clearly, number of poster will increase, money raised will also increased Money Raised 250 x Number of posters sold 60 102 \[\therefore \] \[\frac{250}{60}=\frac{x}{102}\] \[x=\frac{102\times 250}{60}=425\] Money raised by 102 poster is Rs 425. (b) No, class could not raise exactly Rs. 2000. Let the number of poster Anju?s class need to sell be n.
\[\therefore \] \[\frac{250}{60}=\frac{2000}{n}\] Money Raised (in Rs.) 250 2000 No of posters sold 60 n \[n=\frac{2000\times 60}{250}=480\] So, required number of posters are 480.
