Answer 2

Answer:

Ramkali Save Rs. 1920 in one year.

Step-by-step explanation:

Hey Mate,

Given,

Ramkali need Rs. 1800 /- her daughter to start going to school.

Save Rs. 50 in First Month of the Year ( Rs 20 Increase every month )

1st Month = Rs. 50

2nd Month = Rs. 50 + Rs. 20 = Rs. 70

3rd Month = Rs. 70 + Rs. 20 = Rs. 90

4th Month = Rs. 90 + Rs. 20 = Rs. 110 . . . . . . . . . So on.

a ( First term ) = Rs. 50

d ( Difference ) = Rs. 20

n ( No. of months ) = 12

So,

S₁₂ = $\frac{12}{2}[12*50+(12-1)*20]$

S₁₂ = 6 ( 100 + 220 )

S₁₂ = 6 × 320

S₁₂ = 1920.

Ramkali Save Rs. 1920 in one year.
