Monkey required for Ramkali for admission of her daughter =Rs. 2500
Her savings in 12 weeks (in Rs.) are 100, 120,140,160,... upto 12 terms, which is an A.P.
Here, a=100, d=120-100=20
`:.` Sum of savings in 12 weeks `=(12)/(2)[2xx100+(12-1)xx20]`
`=Rs. (12xx210)=Rs. 2520`
So, she will be able to send her daughter as the saved more than the required money.
Value : Small savings can fulfil your big dreams.
