Answer 2

SOLUTION

Let a be the first term and d be the common difference

We know that, sum of first n terms

$= > sn = \frac{n}{2} (2a + (n - 1)d)$

A/q

Saving Ramkali in 1 year= Rs.50+ Rs.70+Rs. 90.......

Here,

a= 50

d= 70-50 = 20

n= 12

Therefore,

S12=) 12/2 [2×50+(12-1)20]

=) 6[100+220]

=) 6× 320

=) Rs.1920

Hence, After a year,she will save Rs.1920

Since, required amount for admission is Rs.1800 and her saving will be Rs.1920.

Thus,

Yes, she will be able to fulfill her dream of sending her daughter to school.
